Twitter widget refresh
The script described may not work anymore.
I couldn’t find anything in the Twitter Embedded Timelines documentation that would let me set refresh interval so I made my own. At first I thought I could simply reset the iframe’s src attribute, which usually would reload frame’s content. But Twitter’s widget didn’t had src attribute.
I found a solution. It’s really quick and dirty one, but it works. You can get and modify it to your needs. I’ve only tested it with list’s timeline.
