A Twitter “party” is a fast and fun way for people to connect and discuss a topic of choice via Twitter. The word “party” is misleading because it’s not an invitation-only – everyone can join in!

Hashtags are simply the symbol # followed by words, are usually placed at the end of a tweet. They were created to help users locate groups or follow a particular context. Create a special Hashtag for your party (Join our party thurs 7-9 pm for great prizes from #threeforone)

You can search for a specific hashtag through Twitter’s Advanced Search option under ‘words’ or in the general search, and easily join in on the conversation. Tweetdeck, Tweetgrid, Tweetchat, and Twhirl make following a Twitter party much easier by filtering hashtags. With Tweetchat, all you do is type the name of the hashtag, and then hit ‘Enter Room’ and it will automatically put your hashtag at the end of every tweet. Anything you post during the party is still publicly visible via Twitter.

Advertise it on you blogs/websites, send out emails, and then Tweet about it so that users will participate.
It’s a great way to build interest and followers while promoting a new service or product.
