More data about the growth of Twitter, this time from the UK. Hitwise has released stats showing that Twitter now gets more site visits than the online editions of UK newspapers.

Though Hitwise measured the newspaper home pages, and a lot of people obviously go straight to the relevant sections or blogs, that’s balanced out by the fact that a lot of Twitter use is now via third party applications like TweetDeck, as opposed to via the Twitter website.

As the chart above shows, most of Twitter’s growth has really come about in the past three months.

Yet, at the same time as the following San Francisco Chronicle diagram about US traffic, it’s still dwarfed by Facebook, which seems to becoming to social networks what Google is to search.
