Notably late yesterday, staffer Mahendra Palsule made a subtle post that he was resigning from another job to work full-time with the Techmeme team. The mention was not made on Twitter. It was made on Google Buzz (which could signal a sign of things to come):
McCarthy, who has been with the 5 person Techmeme team (which also produces 3 others aggregators) will edit Mediagazer.
Other staffers include Rich DeMuro and Lidija Davis.
Rivera took Techmeme from a bot-driven aggregator last year, to one than uses a few 'real people' to fine tune the results.
With the literal definition of 'media' and related delivery platforms changing at a very rapid pace, it should be an interesting challenge to watch as this project as it unfolds over the next few months.
