Not a blog about the everyday lives of superheroes, but a directory of live-action superhero movies and TV shows--whether they're from DC, Marvel, any of the other comics companies, or specifically created for movies or TV. It even includes commercials and fan films. I haven't been through all of it, but it looks pretty extensive. Bear in mind, though, that from reading the synopses, English appears to be the site author's second language. There it is for anyone who's interested.
