Blog aggregators

I've been following the birth (and likely death, too) of Pajamas Media or OSM, the blog portal put together by US megabloggers like Instapundit and Roger Simon. The need for such a service in the US is unclear to me, but it did strike me that there may be a market for something like it in the UK.

Here the mainstream media are obsessed with celebrity, sex, and trivia (and preferably all three at the same time). Is there not a need then for an aggregator of all the serious stories and analysis out there - both MSM and blog-based? I can't be the only one scouring my daily newspaper for the day's important story - there's rarely more than a couple on any given day.

Just an idea.
