I discovered TweepML a while back, it's a great tool if you want to quickly follow a group of people on twitter who all share the same area of expertise or interest as you.

The site has now added the ability to follow all members of a Twitter list as opposed to following the list itself. As far as I'm aware it's the only tool out there which allows you to do this.

You can either whack in the URL of the desired Twitter list or you can create a TweepML from an existing list. If you choose the latter you can create a button making it easy for visitors to your blog to follow everyone on the list with one click.

I tested out the new feature using John Carnell's Third Sector All-Stars Twitter list. Click the button below and you can follow the entire list in seconds (there's a few different buttons to choose from):

As soon as I get Third Sector Blog launched I'll be adding a TweepML button which will allow readers to follow all the blog contributors with just one click.

I'd be interested to hear what others make of this new TweepML feature...Where would you add the button? Is bulk-following ethical?
