I updated siblogs.com a bit. The most notable thing is OPML file. If you have problems with importing the file, let me know.

Q: What is OPML file?
A: OPML stands for Outline Processor Markup Language. In our case it contains the complete si.blogs list and can be used to import the feeds in the aggregators. Just right click on the link, save it to a file on your computer and find an Import command in aggregator of your choice.
