Escolar seems to be a clearinghouse of the Spanish [mostly left] blogosphere. I have not been reading it for that long, but he basically seems to post mostly links to other Spanish blogs, with short excerpts [isn't this what Moon of Alabama  does, too?] and occasional posts by Escolar himself. The centre of the universe for the spanish right-wing internet is Libertad Digital, which is not a blog but an online publication run by Federico Jimenez Losantos, the Spanish Rush Limbaugh.

I have to agree with poemless on a parallel thread that we shouldn't underestimate the power of scoop. I am beginning to believe that the reason the UK (and Spain) blogospheres is so poor in the opinion of many here (just my impression of the Spanish one, I'm sure I'll get flamed for it ;-) s the absence of a dedicated scoop site. The I-post-you-comment model of most blogs is generally a very poor debating environment. For instance, IMHO the addition of a comment section did nothing to improve Juan Cole's blog: it was a necessity brought about by the incresing volume of e-mail he was getting. "Celebrity" (e.g. Wallstrom) blogs are even worse in the quality of their comment sections.
