Twitter has entered the top 50, in at number 42 with an estimated 21.2 Million monthly uniques. Twitter first entered comScore's Top 50 in June '09. Note that comScore probably undercounts Twitter's audience by a lot, because many Twitter users don't visit twitter.com but use third party clients. We reported last week that an estimated 65% of Twitter users still use twitter.com, so it may be undercounted by as much as a third (but it's hard to know for sure, as many people use both the Web and third party apps).

One of the comments mentioned that comScore doesn't take into account SMS which is a big feature for Twitter. Combine that with the 3rd party services and Twitter is a "big deal."

The Internet has become such an essential part of daily life that four out of five (82.8%) respondents say their daily routine would be disrupted if they were without Internet access – 41.3% say their routine would be “significantly disrupted.” Women are more likely than men to say their lives would be “significantly disrupted” – 43.9% versus 39.3%, respectively.

I don't watch much TV = I watch Hulu online
I don't talk on the phone = I IM and VOIP
I don't write letters = I email
So, yeah - my daily routine would be "significantly disrupted".
