Backing-up your stuff is never a back idea, although there’s some debate over whether to choose the cloud or a local harddrive. But if the cloud’s your choice, then there’s a new company to add with BackupMy.Net.
You get to save emails, blogs, pictures, and most importantly here, Twitter. It’s relatively fast, and you can download your tweets in HTML, JSON or XML format.
If you want to ask them a question directly, obviously they’re on Twitter as @backupmymail (not backupmytwitter?)
It’s free to back up your Tweets, no password is required, and their own counter is claiming close to 3 million Tweets are already protected.
The main concern that has been highlighted so far has been ReadWriteWeb pointing out that it auto-Tweets on your behalf.
