I have been using Memeorandum for the past month to get my tech news and making a general comparison to tech news from other aggregators. From a relevancy and timeliness standpoint, I think this is the best site for up-to-date tech news.

I’ll keep an eye on the day-old Gada Be which has some nice virtual URL capabilities (keyword is persisted as host name; add /opml to get OPML of results).
