Roundup : Topify, NutShellMail, tweetworks, PleaseRT.me, WeFollow
Topify - allows you to reply to a direct message from your email, and like Twimailer it mails you lots of information about new people that follow you.
NutShellMail - both OutTwit and Twittermail allow you to tweet by email, the later will also email you any direct messages, replies and timeline (on request). NutShellMail does a similar thing but, rather than emails of new followers as they happen like TwiMailer and Topify, it gives you a handy snapshot or digest of your activity (latest followers, quitters, replies, and tweets). Like Topify (above) you can email reply to direct messages.
tweetworks - create or join a group on Twitter. Unlike twitter hashtag channels, you have to join a group first. All tweets to this group are displayed on the group page, see more on Twitter groups. Not sure if I would like to see this on Twitter; I think this would take away some of the magic. The reason Yammer Groups are handy is that you can limit usage to your team or work on a task.
PleaseRT.me - if you want a tweet heavily re-tweeted, enter it into the PleaseRT.me box and it will send your tweet, along with a link in the tweet to easily retweet it. Then you can go back to PleaseRT.me and check out the stats to see the number of times it has been retweeted.
WeFollow - a user powered Twitter directory, see more.
