I was looking at some blog designs and there seems to be a most blogs that I have seen have only a single sidebar and it's usually on the right side of the pages. I was wondering if it's better to have just a single sidebar on 1 side of the pages on your blog or if 2 was better. What do you think? I didn't know if there was a reason for using a single sidebar vs a 2 sidebar layout. I see so many that have just 1 so I thought there might be some advantage for 1 reason or another.
