From the website:
“Ever wondered why you can’t just click on an article and blog it? Where’s the universal “Blog This” button? […] RedirectThis is a blog-this button that works with any site, routing users to whatever tool they choose. […] RedirectThis solves this problem by sitting between a source blog and a reblog, redirecting users to the reblog of their choice.”
There are 2 choices, hit a button that goes to the RedirectThis website first, or another button which goes direct to your reblog site (the reblog site may be your blog…for the second option you have to add some code to your blog)…how it works.
See the demo.
So basically, it is about taking chunks of microcontent and sending it to another application…this is basically the idea of cut n’ paste (where you are holding the data and looking for a place to put it), whereas with reblogging you are sending the data to a URL.
Check out Live Clipboard, a cut n’ paste tool for the web (copy content and paste it somewhere else).
