Yup, very much so. I bring all the Internet I need right to my LJ; makes keeping up with things very convenient. Like your other commenters, I come here to comment rather than doing it on the feed. People do sometimes comment in feeds, but these often are notes to LJ-ers in general about the article. You get that more in the comic-strip feeds than anywhere else, as far as I can tell. Bloggers who want or need the direct hits to their sites tend to configure their RSS feeds to just post a link to the updated content rather than including that content as well. I don't mind that a bit; the feed behaves as an update notification in that instance, and saves me going around to check the site.
