Microsoft, Sony Compared in XBL, PSN Numbers

[Reasonable]

With PSP and PS3 plus free nature of PSN it's very likely to have more people signed up vs Live, then of course on Live it's only really the smaller number of Gold subscribers who really get all the social stuff anyway.

I think Live still gives the slightly better service overall, but it's pretty close now and certainly neither is leaps and bounds ahead anymore.

Once Live spreads out over Zune, etc. the situation may change, but if you add PSP/PS3 install base you can see the advantage from a pure users point of view PSN has.
