Andrew Gerrard worked on both and apparently didn't think Camlistore was the right basis for what they wanted in Upspin. But I'm sure you, who I'm not sure has used either project, know better than Andrew and Brad and Rob.
Thank you again for the info/backstory, though. I am just a naysayer who has sat through 1000 pitches of Fitzpatrick's basis thesis back in 2010 and seen excruciatingly minimal progress in the space of "actually making these things work for normal people".
Which is it?
At this point, I get the sense that Upspin/Camlistore don’t really _want_ to succeed in terms of catching mass-market success and disrupting the innovation-stifling tech giants. It seems like they’re more interested in scratching their personal itch and being content with that. Totally fine, but I’m going to be slighly less excited about releases from both of these projects in the future unless I get indications that the core team members are willing to escape the same trap that plagues all standardization schemes (https://xkcd.com/927/)
