Reading blogs is basically the same thing as watching the cooking channel. Neither will make you good at what they're displaying but damn is it fun to watch. It's pretty rare that a blog will get any large number of followers if it's actually technical enough to be useful. The blogs that get all the traffic are the utterly useless (from an education point of view) ones.

It's not that blogs don't serve a purpose. They're a great way for both the writer and the readers to stay passionate about what they do and the technical information posted is great when googled. But make no mistake, reading blogs religiously every day will not make you a better programmer. While plenty of above average programmers read lots of blogs I have a feeling that the truly great programmers don't. They're too busy actually coding and learning to waste their time on such pointless drivel as I'm writing now. (Yes, I am fully aware of the irony here.)

It's very easy to get lulled into thinking you're making yourself a better programmer by reading programming blogs. You aren't. Put the feed reader down and pick up a book. A good one. A single book on a topic you're only vaguely familiar with will teach you more useful than than a full year of reading blogs. Do yourself a favor and do like I just recently did. Delete at least half your RSS feed subscriptions, starting with any feeds that have more than one entry a day. You'll have a lot more time and probably spend it a lot better too.
