Up until an hour or so ago, I’ve been blocked from Del.icio.us for nearly two days. I’m sure it was a simple error on their server, but even a support e-mail did nothing fast.
We reminded you a while back to backup your hard drive on cds/dvds/external drive, and now I recommend you do the same with your Del.icio.us account. You never know if their server with your account may go kaput one day, so this 1 minute task would pay off if it happened to.
1) Make sure you’re logged in. Click the settings button.
2) Click export / backup under the bookmarks column.
3) Click the export to html button.
4) Save the webpage it generates to your desktop.

This simple process may save you from the excruciating pain of losing your bookmarks from over the years, or not being to access them for an unknown amount of time.
