Although I really love the concept I can't get the tool to work, really. the only communities I get it to work with are Sametime (full) and LinkedIn (only half-way). Everything else doesn't anything or is generating errors in the log window when trying to update or read feeds. the ones I tried so far are out internal connections server and facebook.
LinkedIn only seems to work half-way: upon first setup it pulled everything from my LinkedIn friends but from then on nothing more. Meanwhile I disabled caching and deleted the cache database, but still all of the feeds pulled upon first access keep re-appearing
