I've been using all these for some time, though I have to say my use of Google Docs is, mainly, not collaborative. I use it as a place to put documents I'm working on and need to use from a variety of locations…much the same as fact, as I use Dropbox, though I only started using the latter last year; I used to use myiDisk for much the same purpose. Looking through the shared items in Google Docs, there are some from my days as Chair of CoFHE LASEC, and one from the work I did with Emma Illingworth, aka @wigglesweets when we organised the first Brighton LibTeachMeet, (at which, by the way, @katiepiatt showed us some nifty things to do with Google forms). I haven't therefore used them to collaborate on any documents with library users, which might be their most fruitful application.
As for wikis, I'm involved in a few. Looking at the list of seven I contribute to in PBWorks, I have to confess I didn't originate any; some are more or less dead, and the one I use the most is the Voices for the Library one, which we use for documents. I also contribute, in a very minor way, to Wikipedia now and then. I have to confess to a couple of problems with wikis: one is that I find the mark-up language a pain to use. It is subtly and annoyingly different from HTML, and my poor brain finds it hard to remember the differences. The other is that, in about ten years of using them, I have yet to find a way to make them an organic part of my daily life…they're always an afterthought. I've used many more as well, mostly support sites for software I use, who have used a wiki to organise support information, not, I'm afraid to say, very successfully. One organisation I'm part of has tried to use a wiki as the basis for its whole web presence. I shan't name them, to spare their blushes, but it is not a rousing success.
