Six weeks ago, ReadWriteWeb published their definitive list of the top Twitter clients. The methodology for that list was watching the Twitter public feed and logging tweet sources. However, how does the list of clients people are using match up the list of the ones people are talking about? Using data from blog search engine Twingly, we decided to see which Twitter clients are getting the most buzz on blogs. The result is a list of the most popular 3rd-party Twitter-apps according to the blogosphere.

This is a guest post from Anton Johansson, a business developer at the Swedish startup Twingly.com, which developing a spam-free blog search engine focused on Europe.

Top 5 Overall

ReadWriteWeb’s public feed study in April also found Twhirl to be the most popular Twitter client. It was helped in the blogosphere by all the buzz created by its acqusition by Seesmic last month. [Incidentally, that also drove a lot of traffic to our Twitter clients list post as well. — Ed.]

Top 5 Desktop Apps

The top two desktop apps — Twhirl and Twitterific — are again the same ones ReadWriteWeb saw last month in their study. But after that, things deviate a bit. Snitter, Tweetr, and Twitteroo were all farther down the list in terms of usage, but are getting a disproportionate amount of coverage in the blogosphere.

Top 5 Web Apps

Launched just a few weeks ago, Twistori (RWW coverage) has already garnered a lot of attention. Interestingly, Twistori actually uses data from Summize, one of the more popular Twitter search engines — and clearly one of the most talked about, as well.

Top 5 Mobile Apps

There have been far fewer blog posts written about mobile Twitter applications in relation to other categories. Hahlo, the first iPhone and iPod Touch client for Twitter takes first place in terms of buzz, followed by Cetwit, a popular app for Windows Mobile. Twittai is a Java-based Twitter cell phone application.

Notes and Methodology:

We used the the list of Twitter apps on the Twitter Fan Wiki as our source of applications to watch for. The list contains 209 Twitter apps, most of which have not been linked to from the blogosphere at all.

LoudTwitter, an app that publishes tweets to blogs, was excluded because most of its links came from link backs included when the service pushes tweets to blog posts. They didn’t get many mentions in posts specifically about them, but their autolinks generated a ton of links within the blogosphere.
