Used to be the only way to find out what was going on in your town was to check the local paper or TV Guide. Now the local paper offers thousands of events online, and hundreds of internet sites can tell you what's going on, when, and who else is going. And event aggregators scrape the the web for you, so you can find events from around the country or just what's happening at the local bar. Now the only question is, what do you want to do tonight?
