Twitter is quickly inserting itself into the political mainstream, helping to extract American travelers from sticky situations abroad and even giving members of Congress a way to connect with their constituents. Now, Footnoted blogger Michelle Leder has discovered that the Securities and Exchange Commission has its very own Twitter feed. Under the moniker SEC_Investor_Ed, the SEC has been posting updates since late July of this year. As Leder notes, the SEC's Tweets are basically a condensed selection of the (not really all that exciting) press releases available on the organization's Web site, and it was started the day before the SEC voted unanimously to provide new guidelines for public companies' Web pages. Still, someone must be interested: So far, 275 followers have subscribed to the feed.
