Throwing a great tweetup isn't as easy as throwing a great party (where free alcohol= good time). Ok, maybe it is.

Regardless of the alcohol availability, here are a few ideas to throw a great tweetup.

• Partnering with a conference to get on the official schedule
• Hosting at a bar — offer 2 free drink tickets with registration at the door and free appetizers. Get e-mail address and twitter accounts here
• Have it at a bar near or in the hotel where everyone is staying
• iPad’s or some other technology on hand where people can sign up for your service
• Use a hashtag that you promote via blog post and Twitter prior to the event
• Post the hashtag on posters at the event
• Wifi (I've been to a tweetup with no wifi — can you say disaster?)
• Nametags — encourage people to write name AND twitter username
• Use a tool like Eventbrite for online registration
• No presentations- people come to mingle, not listen to another speaker
• Communicate! — Big details like theme down to small details and reminders like bringing business cards, etc

What's the best tweetup you've attended? What made it great?
