I don’t have any books to recommend right now, but I do have a recommendation about an easy way to keep up with your friends’ blogs and websites.
If you use an online “site aggregator” like Google Reader, you can subscribe to your friends’ websites and blogs and be notified whenever new content is published. This saves you the time of having to go to each of your friends’ sites one-by-one and check if they have added anything new.
Google Reader uses RSS (Really Simple Syndication) to keep track of your favourite blogs. If you are unfamiliar with RSS, here is an excellent video to help you understand why RSS is your new best friend.
Once you have signed up for a Google account, you can set yourself up with Google Reader and then every time you see an RSS logo (which looks like this) on a site that you like, you can click on it and add it to your Reader.
