TBH I'm not super invested in github. I pay for it (smallest plan) and use it as a repository and for forking other projects occasionally, and for hosting some small-time static sites. I've never really needed any of it's other features. Every time I go to github.com there's more and more cruft though, which to me means that I'm not their target customer and they will inevitably either alienate me or jack up their prices. Happens every time there's an acquisition so I'm kind of used to it now.
Github has remained surprisingly useful for quite a while post M$ purchase, but I'm old enough to know that everything M$ touches eventually goes to crap. It's like a law.
I remember using CVS and Subversion though, with very limited hosted options, and I thought Github was the bees knees at the time.
I am 22095 on GH but 213 on Sourceforge :-D I have a 5 digit user id on Slashdot as well (~20k mark if I recall).
