You are looking at old and broken stuff - head over to my blog or my posterous.
I turned off polling the sources, so everything you read here is outdated. I'll possibly build a version that pulls entries via JavaScript on the client.
The maps widget is broken since plazes.com died a slow death after being aquired by Nokia; the del.icio.us posts don't work with the current API. You can still access the links via the tag library.
But seriously, if you care, you should probably rather get a live.
