Well I rarely turn mine on anymore ...It 's buried in a drawer around here somewhere. I have only so much time. I've been focusing on my N8x0's and my N900 and primarily either helping new members, trying to encourage devel in the maemo4 end of the pool, doing work on peripheral gadgetry for the n8x0 and n900, or trying to do work-work.
Haven't the juggle room myself.
I'd probably use my 770 more if the was any movement development-wise over the last handful of years...but it's been a long time since anything new happen for it.
Of course that is not to say I haven't run into people over the last year joining up as new maemo members with their 770 in hand or the odd old member chiming-in on a topic now and again.

Your best bet is to post it in the subforums that would get the requisite attention.
If you post the same question in the 770 subforums you'll get their interest.
It may take a long time for them to notice.
I would imagine none of the active (or dormant ones for that matter...) 770 users would be expecting something new.
Just be prepared for the fact it may take a while for responses to start trickling in for your query for testing and for offering a new player ....
