Tweetwall is an interesting new service that lets you create a stream of tweets based on hashtags, usernames, and keywords. It’s cool because right now you can only create a real-time list of tweets on Twitter by perform a search on one keyword. Here you can add several keywords, several usernames, and multiple hashtags and Tweetwall will combine all those into one single stream, or “tweetwall”. You can then share it with anyone.
