@jesseplusplus Probably not. I think I had a very romantic idea of how powerful Open Source and open standards were at that time -- that they would inevitably wash away proprietary, siloed systems. It's also worth noting that there were hundreds of Twitter-like services, and Facebook-like services, and so on during that period. So the idea of federating them made a lot of sense.
@jesseplusplus I had a much more pessimistic feeling about federation by the early 2010s, when that ecosystem had collapsed into a few dominant players. It wasn't until we started the Social Web Working Group at the W3C in 2014 that I started feeling optimistic again -- and even then, I expected the social web to be mostly enterprise social networks, small open source networks, etc. The entry of major commercial social networks has been a big and welcome surprise.
