WASHINGTON (CNN) - While confirmation hearings for Sonia Sotomayor are dominating the airwaves and some of the most-trafficked blogs on the Web, it seems like there's not much buzz being generated anywhere else.

Today, "#Sotomayor" - the hash tag used on Twitter to easily search for tweets about the hearings - has been rotating on and off Twitter's top "Trending Topics," while "Harry Potter," "Bruno" and even much older hot topics such as "#iranelection" have been constantly populating the site's top words to appear on Twitter.

It even seems like Judiciary Committee senators may not be all that interested in tweeting about the hearings. Republican Tom Coburn (@TomCoburn) tweeted today about a new "Pork Report," and told his followers to keep their eyes on for the "health care reform debate" – but made no mention of Sotomayor. Democrat Russ Feingold's (@RussFeingold) last tweet came on July 10.

There were a few Judiciary Committee senators on Twitter who did make mention of the hearings. GOP Sen. Lindsey Graham's team did tweet from his Twitter account (@GrahamBlog) about the hearings, which also rated a few mentions from Republican Orrin Hatch (@OrrinHatch).

Hatch tweeted: "Our current gov is so-far removed from the limited gov that our Founding Fathers intended that they must be rolling over in their graves." Hatch also wrote: "Listening to both sides during Day 1 of the Sotomayor hearing proved 1 thing-the battle over judges is not merely a philosophical battle..."

Republican-turned-Democrat Arlen Specter (@SenArlenSpecter) weighed in as well during the hearings: "I think it was wrong for America to wait until 1967 to have an African American justice, Thurgood Marshall, on the court."

Elsewhere on the Web, interest in the hearings seems to have faded. By the end of the day, Google Trends ranked only three Sotomayor-related searches among its top 50.
