I use Google Reader, because I want to know when there's new stuff on certain sites without visiting them all, but I don't like it that much. I prefer to read the stories on the web site, with its "native" formatting and whatnot. Is there a tool in any of the common browsers that will highlight a bookmark (or something like that) when there's new content on the site? I think I'd greatly prefer that to the whole business of using a feed reader. Am I the only one?
