modern horror anthologies

I have a question for you, what do you think about modern horror anthologies like The mammoth book of best new horror edited by Stephen Jones, The best horror of the year edited by Ellen Datlow or Paula Guran The year's best dark fantasy and horror? are them interesting enough? worth reading?

I think that all three are generally well worth reading. They don't overlap that much, which reflects differences in their personal tastes, so it's possible you'd like one or two more than the other(s). You won't like every single story in any of them, but the level of quality is really high. Next year there will be another entry in the best-ofs, edited by Laird Barron.

an anthology edited by Laird Barron!!!??? could be awesome... have you got more info?

ollonois, go to Undertow Books, run by the excellent Michael Kelly:

Scroll down past the Joel Lane remembrance (sad news) to some entries about the Barron Best-Of.

Here's some more info on the Barron volume, in this interview:

I don't know about the specific ones you mentioned, but I have the Mammoth Book of Wolf Men edited by Stephen Jones and enjoyed it quite a bit. With a collection, I think there will always be a few stories you don't like.
