Six years ago, Firinel had an idea: would it be possible to track who had friended and unfriended you on LiveJournal over time? I was inspired to work on a project to answer the question, which became Joule. Today I released Joule 3.5, which adds Twitter support— and identi.ca, too. In other words, it’s possible to chart who’s following you on either service. It’s useful to me and thousands of others, and I thought it might be useful to some of you.
Update: Forgot to mention: you can also get RSS feeds out of it.
