Here at ReadWriteWeb we spend a lot of time reading the blogs of companies we write about (send yours to tips@readwriteweb.com) and we've found that some of them are just plain fun. An interesting company blog can be a great way to draw in new people through relevant content of general interest - and some of them will stay to check out the service you provide.

Some companies just blog about updates to their own technology and that's good for existing users to see. Others are fun to read whether you're a user or not. Here are some of the company blogs we recommend reading for a good time.

You can't talk about interesting company blogs without mentioning Signal vs. Noise, the wildly successful blog about design, usability and small business from the makers of project management service Basecamp. This blog could easily stand on its own as compelling reading even if there wasn't a company behind it selling services. Sure enough, it's even got an ad on it from the elite boutique ad network The Deck. Signal vs. Noise has 88k subscribers - making it fun
