How Are People Twittering on Twitter ? Google Tells It All
There are a few dozen ways to publish tweets on Twitter. You can post from your mobile phone (SMS), Google Talk, Facebook, Firefox, desktop or directly on the Twitter.com website.
With so many different options in place, have you ever wondered what tools are really popular among the Twitter community ? While there no official statistics available, the thousands of public Twitter profiles indexed by Google paint a fairly accurate picture.
Here are the results based on 105k Twitter profiles indexed by Google:

1. A very large majority (70k) of Twitter members change their status from the Twitter site itself. The next popular "official" method is IM followed by SMS which is at distant third. See graph.
2. Twitterrific almost rules the unofficial Twitter software market. Other clients like Snitter, Twhirl, Twitbin, Pockettweets, etc have more or less the same number of users.
3. It is quite surprising that Twitter Opera widget and OutTwit (Twitter add-in for Microsoft Outlook) have a fairly small user base.
4. Some 700 bloggers are using the Twitterfeed service to automatically update Twitter as soon as they publish a new blog post.
How we came up with these numbers ?
When you post on Twitter, your message (or tweet) contains the name of the tool you used to publish that update. For instance, if you update Twitter from the Netvibes widget, your message will read something like "about x hours ago from Netvibes".

Since this information is also indexed by Google, you can easily guess the popularity levels of various Twitter software with a simple Google query:
site:twitter.com -inurl:with_friends -inurl:statuses -inurl:favorites "ago from Facebook" - just substitute Facebook with a different client like "twitterrific", "im", "snitter" "txt" (for mobile phone updates), etc.
There could be minor variations because not all Twitter profiles are public and lot of people may be using multiple way to update their Twitter status.

This is fairly inaccurate data.
It is based on Google search results, which is a dubious data point. Google drops a ton of tweets in its search results.
“ago from xyz” is not the right search term. Indexed tweets, older than 24 hours, do not contain the word “ago” in them.
I’ve heard that the servers are moving to a new hosting too. Hope that solves the downtime problem. Glad to see my favorite Twitter client - Snitter is on the top 10 list.
now they also have a India specific short code 5566511
I actually came upon your article from a twit :) I didn’t know there where so many Twitter clients out there and Twitter is very new to me. Your article was really enlightening. Thanks! :)

Its fairly better now.
I just searched for Twittermail.com and they scored 257. Not much but more than the less popular clients shown here.
