If you're trying to turn your startup into YouTube-sized fame, not Vimeo-sized fame (or is that Hulu-sized fame, now?) then where do you turn to figure out all of that post-LLC/pre-IPO nonsense? Two of tonight's events deal with your precious baby startup: if you're looking at the legal issues facing startups, SCORE will be hosting a workshop with lawyers telling you what you're doing wrong. Going the cheap route and advertising your startup on social networks, not billboard ads? SVASE is telling you how to suck social networking dry for every (targeted ad) penny that you're generating. BayLISA's June meeting is happening tonight over at Yahoo! HQ in Sunnyvale and will be talking Apache Hadoop.
