What are the best industry Expos/Tradeshows?

I am interested in Expos and trade shows relating to the IT industry.

I know about Web 2.0 Expo and Summit, and I just came across sxsw, http://sxsw.com/interactive , but are there any other big Expos that are worth keeping an eye out for? Particularly stuff on the East Coast?

Any expos that focus mostly on the Web. Design, Development, Programming, Marketing, etc, etc.

Here’s a list of conferences which may be of interest (their all over the place though):

Thank you! That’s exactly what I was looking for. There seems to be some real nice shows coming up within driving distance for me and my coworkers, so hopefully I will be attending a few of these :slight_smile:
