Blogs used to suck. And, in fact, most of them still do. That is, unless you are some avid personal historian who loves to hear the mundane day-to-day of several million less than exciting average everyday people. Thank goodness for failblog and awkwardfamilyphotos and lolcatz and satire blogs like the onion and this one. They will give you more than your fill of inane drivel and hilarious things that don't make sense. And really, isn't that what we all want? To be entertained? If a blog is not entertaining, why the heck are you going to read it? To catch up? To make yourself feel less guilty when your friend asks you if they've read your blog?
You should read a blog because it is interesting, and because the writer is a) creative b) funny c) not going to tell you a play-by-play of every waking moment of their boring life or d) because you like the pictures/movies and random media tidbits. I hope I have done my job. Those are my two cents. Don't spend it all in one place (unless it is this blog), and then I say you read and enjoy all the posts, click a million times on all of the ads, and even buy things you find interesting. Or, you can do whatever the heck you want, which you'll probably do anyway.
