Memeorandum, which to date has focused on tech and politics, is wisely starting to branch out horizontally with new vertical sites.

The first, WeSmirch, rolls up celebrity gossip from blogs and news sites every five minutes. Digg has expressed an interest in going the same route in the near future.

I believe the memmtrackers will reach a critical mass in the next 12-24 months and will begin to gain market share from traditional news aggregation sites like Google News and others. Wired News hints at this today. The reason is some people have a desire to dig deeper in the areas they care about. The memetrackers help fulfill this role. They are fueled around high-interest topics and they could dramatically alter how millions consume news and information online.
