Hi Chris,
It's frustrating that the these silos ask for the information to build a profile page but don't use microformats. They are indeed silos of information. I setup the first 40+ profiles on my site and then gave up adding the rest when I realised how few were linking back. I don't quite have 200+ profiles but it's a lot more than 43.

If twitter can support rel=me then it's quite odd that keybase.io does not. I read Kevin Mark's article and I will try out his Chrome browser extension. I am still working on why no rel=me links could be found on my Google+ profile. I was sure Google+ supported this.

Incidentally, one of the benefits the rel=”me” links do have is that they allow you to use your website to log into the IndieWeb wiki to participate directly in that part of the community. (Give it a try!)

I did just that this weekend. I put an entry under the Generation 1 / Generation 2 section of the Generations page and RSVP to the Virtual Americas HWC.

Thanks for the links to Ryan Barrett and XFN friends network. This is all so exciting (and frustrating).
