Track Twitter search results, a Twitter hashtag, or a Twitter profile using sidebar widgets.
A widget, Twitter Search Tracker, which allows you to specify and display a Twitter search (or a Twitter hashtag) in your sidebar. Twitter searches are very flexible, and you can display anything from Hashtags to individual, or aggregated Twitter streams.
Another widget, Twitter Profile Tracker, allows you to show the tweets from a specific user in your sidebar.
With the profile and search widget, you can choose to only show tweets with a particular hashtag, to control which tweets get shown on your site. You can also elect not to show retweets or "@" replies.
