The last SearchSIG event I attended was really good and the lineup for this next event looks interesting as well. Presenting companies include Edgeio, Google, and Oodle with others to be added later. Sounds like a good list of presenting companies — it would be great to add someone from Craigslist in the mix.
I worked at Excite for a brief spell and am glad to see some former Excite people up to interesting stuff.
If you are going to the event and would like to meet up, email me. I will probably post something about it after the fact.
