most popular twitter clients for iPhone?

I’m starting to use Twitter more, and so I was curious: which Twitter clients have found favor on the iPhone?  Given the excitement over the new iPhone, I decided to mine some information to find out.  Caveat: I don’t pretend that this is scientific, merely indicative.

On Twitter, I did a search for “iPhone line” and was rewarded with many tweets from people standing in line waiting for the new iPhone, reporting on lines of people waiting for the new iPhone, or (often) deriding people who even contemplated getting an iPhone.  I gathered 380 tweets, extracted all the lines that read “nn seconds ago from client_name” and tallied them by client_name.  Results after the jump:

93    web
69    TweetDeck
66    Tweetie
26    TwitterFon
21    txt
17    Twitterrific
16    twitterfeed
9    twhirl
7    mobile web
7    TwitterFox
7    HootSuite
5    twidroid
4    TwitterBerry
4    TwitPic
4    Flickr
3    Twittelator
3    Seesmic Desktop
3    Nambu
2    vlingo
2    digsby
2    UberTwitter
2    Twitterena
2    TwitterMail
2    TinyTwitter
2    Adium
1    Ping.fm
1    Movatter
1    Godark

Of course, not all of the tweets originated from iPhone clients, but it’s clear that TweetDeck, Tweetie and TwitterFon lead the pack.

Question: Is there a dark horse — one that deserves more recognition than it’s getting?
