Blog surfing. There are so many, I would rather not mention all of them
Google. On a normal day, I might search using Google anything like 5 to 10 times
Google News. This is really cool. I read world news, then India news.
Anchorage Daily News. This might come as a surprise. I would not want to miss any news related to environment of Alaska. I have been a great fan of the place after I visited it.
I am surprised the list is pretty small, considering that I browse a lot everyday.
Categorywise, I most frequesntly visit news sites and weblogs, followed by sites that have anything to do with photography, environment, travelling, adventures and stuff like that.
Once upon a time, the list of frequented sites included stock market related and technology related sites. I might visit websites on markets again but I think technology is passe. :-)
