I’ve hacked in the sharethis thingy, but I’ve only put it onto the full post page, through a combination of not wanting to have to hack the complex mandigo template too much and because I guess if anyone cares enough to want to share they’ll be reading the post / comments anyway.
This leaves me really only missing the OpenID stuff. I signed up for an OpenID elsewhere, and have made this site my ID by delegating it (I think that’s the terminology) so I can log in to places like LiveJournal as perceptionistruth.com to continue harassing my blogging friends there. I looked at adding OpenID support to this site so people can log in to comment, but for now I’m just leaving the comments open.
