Pretty sure (but can't find source at the moment) that that number only reflects the cables on the wikileaks website itself. The number of cables released to newspapers is significantly higher but not a quarter million.
According to a Guardian video I watched yesterday, all of their (the Guardian's) stories so far have been based on "a couple of hundred" cables, which seems to suggest the media does not have to full set yet either.
Oh, gossip is not boring, that’s what’s so devious about it.
I don’t know about eye-opening, though. There are interesting pieces here and there, nothing good journalists didn’t already know or (in the best case for Wikileaks) suspect. Much is nice padding material for articles journalists have already written, another piece of evidence. Nice to have but no game changer.
I like Wikileaks, I really do, but it’s very hard for me to convince myself that this leak is in any way a big deal.
