More on Retweeting 

The Science of ReTweets

Dan Zarrella explains which factors make certain tweets more viral than others.

DailyRT

DailyRT seeks to rank tweets by the number of retweets they've received: it's basically DiggDigg reviews for retweets. It supports Sign In with Twitter, so you can retweet right there on the site, and also tracks retweets of Twitter trends. The key feature, however, is one many trend sites lack: the ability to search and find top retweeted topics from the past. When you log in, you can also save these searches.

If you're looking to see what's hot on Twitter, these new sites are a huge help: DailyRT is a very competent effort and definitely one to watch.

Repeets

Newcomer Repeets tracks hot retweets from today, this week and this month. It also captures all the retweets in a thread and produces trend graphs showing what time a retweet peaked.

It adds a neat new feature, too: you can search by username and see how many times a user's Tweets have been RT'd, along with a roundup of their most retweeted content.

Please Retweet Me

Retweeting is a cornerstone of Twitter use. Twitter users love to retweet great articles and clever comments. But sometimes there are articles or specific causes that tweeters just want to be shared, so Twitter users ask for a retweet. Enter Please Retweet Me, a simple tool that adds a special link to the end of any tweet that, when clicked, will automatically fill in all of the information needed to retweet.

re-Twit'd

re-Twit'd is a simple application that lets you see what's hot on Twitter based on how frequently something is retweeted.

Twitter Apps 

Tools/Utilities

Tweexchange

How much is your Twitter username worth? $300? $400? $1000?

With only a limited number of Twitter names available and many of the good ones already taken, it was perhaps inevitable that a market would spring up for Twitter username sales.

That was the thought that occurred to Craig Agranoff, one of the founders of the crowdsourcing site VOIS.com: today he's launching an aftermarket for Twitter names at Tweexchange.com. (Incidentally, Agranoff claims to have hired a developer for the project through the VOIS service itself for under $1000.)

Twiddeo

When it comes to sharing videos on Twitter, Twiddeo's certainly a viable option, as long as you're not the type to judge a book by its cover. The aesthetically unappealing site comes with the basics for Twitter video sharing, so you can upload, email, or record (via webcam) your videos for instant sharing with your Twitter network.

Video pages are pretty sparse, but you can leave comments (powered by Disqus), grab embed codes, and get a glimpse of all the videos that a user has shared.

What you get in extra features from Twitc comes with a cost. It takes more than just a few steps to actually tweet a video
