Techmeme's definition of "interesting" is "selected by an algorithm that starts with hubs that Gabe says are interesting". If 65% of the stories are written by women, and only 16% of Techmeme's stories are, then Gabe's algorithm finds women a lot less interesting than men.
If you agree, then yeah, Techmeme's awesome.
If you don't agree, then you need to be conscious that Techmeme's presenting you a skewed view of the world. Unless you're actively working to balance it with sources skewed in the other direction then it's going to mean that your overall information sources aren't giving you an accurate picture of reality.
If you looked at the top 5 Google results across all key words and men wrote more of the posts than women, would you accuse Google of bias? Or would you consider that maybe its evidence there are more men writing on the web than women. I don't see a difference here. Gabe's said that his system adds new sources programmatically as they get linked to. Why on earth would he block out female voices?
It depends on how much more. Women write roughly as much as men in the blogosphere, so if the overall results were (say) 75% male it would indicate a bias. The times I've looked at Techmeme and memeorandum they're usually 80-90% male.
I don't know why Gabe blocks out female voices but from the Atlantic article linked to in my thread he doesn't seem to read any women regularly so my guess is that he either (a) doesn't know he's doing it or (b) doesn't care.
