Another one of my top web comics which unfortunately is no longer being regularly updated is UserFriendly.org the story of a small Internet provider and its crazy assortment of staff members. If you haven't already read it there is like 4 or 5 years worth of back issues to get through which are often hilarious and sometimes touching.
An up and coming web comic that I am nearly caught up on is Between Failures which is about the staff of a DVD, Book and game chain store. This seems to be a bit of a running theme in web comics centering them around a place of business which is understandable when it works out this well.
So there are some web comics you might want to check out thanks for reading.
