I can be reached a number of ways besides leaving a comment here on this blog.
Status.net is a federated rich microblogging platform built on Free/Open Source Software. Being federated, it supports personal installations and remote contacts. Identi.ca is one such installation, open to public sign-up. I should also give special mention to the parlementum.net server, run by Charles Roth. He's a great guy, and I'm sure you can get a parlementium status.net account by emailing him at firstname.lastname@example.org
Diaspora* is a decentralized social network that facilitates data privacy and controllable sharing. Though currently it is alpha software, it is Free and Open Source, allowing anyone to set up their own pod. The official pod, joindiaspora.com, is invite only to manage load on the servers. If you want, I can hook you up with an invite to that pod, but there are also several open, community run pods that are up-to-date, such as diasp.org.
