Twittbot is an interesting Twitter companion service that allows you to create Twitter groups. First you create a new Twitter account to represent your group. Then you head over to Twittbot and bind the Twitter account to a Twittbot, picking a security level (anyone can post, or just a few invited users can post). Now anyone (or anyone with permission, depending on your security type) can @reply your group account, and the message will be reposted to the group account.
I heard about this interesting service via Darren Rowse’s TwiTip blog, and decided to check it out. I set it up, and created the open @webmasterlinks group. The group is a place to share links that would be of interest to Webmaster-Source readers via Twitter. If you find something worthy of webmasters’ interest online, or if you create such a thing, by all means tweet it to @webmasterlinks. I follow the group, and if something catches my attention it may earn a mention on Webmaster-Source, or a retweet at least.
