I am building my own microblogging tool. It uses RSS and RSScloud to get realtime updates from the web. Tonight I got it working and now I need some feeds to parse. Yesterday I already saw that Identi.ca provides RSScloud feeds, so I tried one of them out.
The first feed I added was my own. The test to see if it worked was posting a message to my account. And ... a post appeared in my microblogging client in realtime. It only took two seconds between a post on identi.ca and the receive on my end. Really nice.
