Just some feedback from a longtime SP'er. Prior to the implementation of "plans and partners" (boy it's been a few years, eh?) it was always easy to find the latest folks looking for partners- just go to your region and look! Yes, sometimes when you were wanting to find out latest conditions or flip through the recent questions it was annoying to see "NEED PARTNER, JTREE, TODAY" posts, but.... it was worth it for the times those posts paid off.
Now? People simply don't come to summitpost to find partners anymore. A recent search of "plans and partners" within 50 miles of Berkeley, CA revealed just TWO, count them, TWO posts in the current calendar year (which is almost over). That seems absurd, given that the Bay Area is amongst the most outdoorsy-locales in the country, and certainly the most plugged in. You'd figure it would be a hotbed of plugged-in outdoor types, searching for partners. And it is, just not at summitpost. The Plans and Partners interface is clunky, it is not ever updated (so there's still requests from 2006 cluttering up the works), and it's just not useful.
If it was thought that the partner requests somehow "cluttered" the regional boards, then there should be simple, traditional message boards elsewhere for finding partners. The alternative, which we have now, is that summitpost has become largely irrelevant in the fairly widespread domain of internet-outdoor-partner-finding.
This sounds tongue-in-cheek, but it's not. I lament the loss of finding partners on summitpost; back in the day, it was one of the primary reasons to come to this corner of the web.
