I've launched two new beta features for Topicala: Topicala Popular and Topicala People. Topicala Popular helps you discover trending content online, similar to Digg or Delicious, by tracking site visitors via an embedded image. Topicala People helps you find people online using hCard microformats. You can get your information on Topicala People by wrapping it in hCards and either including the Topicala image or pinging our server. These features will soon integrate directly into Topicala's main search. Try them out and let me know your feedback!
I've started gathering hCard stats on topicala.com thanks to pingerati.net. hCards are a machine-readable microformat for contact information that can be embedded in HTML. Pingerati notifies services like mine when hCards are updated. To get your hCard included in the stats, ping pingerati at http://pingerati.net/ping/[your updated url]. I'm excited about the potential of microformats and plan to add more services to topicala as more data becomes available. Learn how to create an hCard at http://microformats.org/code/hcard/creator.
I've added hCard, a microformat, to my blog. It makes my contact info machine-readable while still being visible to readers. It's basically an XHTML version of the vCard standard. I'm not totally sure I implemented it perfectly with the DIVs and spans, but check out the hCard creator tool if you're interested.
