The Twitter Widget displays a feed of recent tweets. The example below is displaying tweets from @HarvardResearch.
Once you create a Twitter widget, you can choose to display the most recent feeds from a Twitter username, hashtag, or search a search term to be shown in the box. You can also give the widget a unique name and description as well as control how many tweets you want to appear. You can also encourage visitors to follow you by checking the “include a follow me” link option.
