Blog hopping IS NOT surfing the net and reading some blogs here and there at random. Blog hopping is when you find a few blogs that you think are really cool, written by people you can really relate to and you visit them regularly. These people feel a special bond towards each other and visit and comment on the blogs in their circle daily!
Blog hopping is when people surf the net and find blogs that our their favorites. They visit them daily and forge virtual friendships with the author of the blog and the other blog visitors. It makes their day brighter and gives then something to look forward to!
When you look at someone else's space, if they have choosen to add an updated space list you can 'hop' from one blog to another reading through peoples comments - most of which are not even worthy of being on the internet.
Some people like to make a game of it -seeing how many Spaces you can get too until there are no other links to another spaces. I have no idea why this is a form of entertainment, but meh, it keeps the plebs off the streets.
