The Kenwood on ISS is very simple to use with the preset PMs and channels (two button pushes to start talking). The Ericsson (GE MP/A) is still onboard the ISS with its simple knobs and channels so it too is available for use by any crewmember. I do not think complexity is a reason for them not being active.
The Shuttle missions were very short duration so they were crammed packed with activities and the crews were geared to get as much done as possible in short periods of time. The first few SAREX missions were initiated by ham radio operators that were astronauts. The later were astronauts who got licensed to support the educational contacts and sometimes made random contacts during periods of off duty time. Back then, the Shuttle crews didn't have email, DVDs or the IP Phone so the ham radio was a way to have contact with folks on the ground.
The ISS missions are long duration and the crews work at a bit more relaxed pace and have a reasonable amount of free time. They also have a lot more choices of what they can do during that free time than their Shuttle counterparts had. Many enjoy taking photos, reading and sending emails, reading electronic books, watching DVDs and talking to friends on the IP Phone in addition to video teleconferences with their family. With all those choices, they don't use the ham radio unless they are making educational contacts, actually interested in talking to people on the ground or nearing the end of their mission and become curious.
We will have other interested crew members in the future so you may have a shot at an astronaut on orbit QSO but I agree that they are few and far between. Think of them as rare DX, patience and preparedness usually will get you the contact.

It depends on the crew how active the ISS is. The current crew is not very active. When they are, you can find them on 2 meters.
It seems that during SAREX, more crews were active. ISS crews seem either a lot busier (less personal time for ham radio?) or are generally a lot less interested -- other than the few "superstars" who usually were already hams or had always wanted to be before going to ISS. I would hazard a guess that those few astronauts who enjoyed working the station on ISS have probably worked far more contacts than the rest of the crews combined.
I understand and am not complaining in any way -- just an observation of how it seems to work out these days.
There are quite a few more school contacts too, and those are certainly a great way to get involved and help a school out at the same time. Engineering a good setup for a school contact seems like it would be a neat challenge for many here on the list.
Additionally, I often wonder if the switch to using the Kenwood had a negative effect by accident. Reading up on the ISS station details, I think it's been excellent for having more options for pre-configured modes, but I think that reading between the lines on some of the posts/ updates from folks who are "in the know" on the ARISS team, I am led to believe that some of the Astronauts are wary of the more complex Kenwood setup.
It was REALLY hard to screw up the GE MP/A's that flew during SAREX... all they had was a rotary channel selector on top, a PTT on the headset cord, and a power switch. There's always something to be said for a simple user interface and the KISS principle. They were pre- programmed and virtually nothing could "go wrong". They were very simple compared to the Kenwood, which is a typical "ham" rig. Lots of buttons, modes and "stuff" that most astronauts simply don't have time for.
Sitting here looking at my VHF MP/A, and I find myself still using it quite often -- radios originally built for Public Safety/Commercial applications just have a lot less "stuff" to mess with and or to worry about "messing up". (And it was great to see the venerable old MP/A in the IMAX footage quite some time ago.)
I've often wondered if the current crop of astronauts feels a little "intimidated' by the Kenwood station?
Of course, other (sad) options might be that with MS Outlook (and crappy .pst files being transferred up/down) handling the e-mail chores these days, (complete with constant crashes and reboots of laptops... seems like it's about time someone put a real mail server on-board... Postfix would do nicely along with a ton of other options) they don't feel as much need for a way to "reconnect" with folks down here on Terra.
It could also be that the current generation of astronauts grew up in the post-radio-awe era (without a better name for it) where they just don't have that same feeling about the "magic of radio" that we do.
Just thoughts... nothing negative meant by any of the above.
The only long-term question/thought would be that it might be a good idea if radio station changes are ever planned in the future -- perhaps space-qualifying something a little less "complex" than a typical ham-grade Kenwood... which I hear is an expensive process (and generally a pain to do anyway)... might help. Numbered channels pre- programmed is the typical astronaut's level of understanding of the radio gear... other than their flight training... but even when flying aircraft, the button to set the radio frequency does ONE thing at a time... the Kenwood dual-bander probably "looks" complex to someone who's never used one before.
The cross-band repeat mode of the Kenwood certainly has been indispensable when it's been active, though -- and that's not going to be found in anything commercial really. Not without going to two rigs and associated cabling mess.)
Just thinking out loud. I have no association or input to anyone on the ARISS team, nor do I have any clue just how hard it is to get a ham rig through NASA's qualification programs and safety programs.
ARISS does a GREAT job even just having us "on board". Thanks guys. It's one of the only ways us astronaut "wanna-bees" can say we've ever interacted in a personal way with ISS... otherwise it's just something we know is up there and can see during certain passes when the sun angles are right. Watching the construction on NASA TV just isn't the same as having talked to someone "up there".
