One of the more popular posts on this blog is the one which describes how to import trips from TripIt into Dopplr, in order to avoid the re-entry tax. After all, as I wrote in my comparison of the two services last October, TripIt’s email import was the critical factor in my decision of how to manage this information: Tripit’s mechanism for adding trips is superior.

Identi.ca is a new micro-blogging service which runs the open source Laconica platform. Ultimately, this will likely be the distributed, open microblogging platform twitter fans have been waiting for (though the community itself seems mostly to be sticking with Twitter, fail whale and all). For now, it’s just fun to play around with. I just release an Identi.ca action stream plugin - get version 1.0 on my Movable Type Action Streams Plugins page. Here’s what the output looks like:

Postica's a latecomer to the free online sticky notes arena, but it carries with it a few neat features that set it apart. First and foremost is the ability to attach any kind of file (up to 5 MB) to...
