RSS news feed
You don't have to check some websites several times a day. You can create as many RSS accounts as you want and recieve update of your favourite websites whenever it is released. Fortunately most of famous websites and weblogs support RSS feed. BBC started this service recently for Farsi news. You can recieve news and post from BBC English, BBC Farsi, Yahoo and so on, or in the field of LIS you can recieve new posts from Open Access weblog and a couple of other weblogs. I strongly recommend your using Thunderbird. Try it, you'll enjoy it.
