I’m on Manton‘s cool new microblogs system. Here’s where you can follow me, once you’re on the system: http://micro.blog/brentsimmons.
And here’s my microblog: http://brent.micro.blog/. (Which you can read using RSS, whether you’re on the system or not.)
I wrote about three-quarters of my own single-user microblog system — and then stopped because I didn’t feel like running a server and because Manton’s service is so good.
