1) Unnecessarily or tediously flitting from one blog to the next in order to leave comments that are repetitive in nature.
2) Leaving quick comments on a large number of blogs for the purpose of raising awareness of the blog-hopper's own blog.
3) Quickly perusing several different blogs that are currently dealing with a similar subject.

"Time to do a little blog-hoppin' in order to get people to discover my blog!"
"I wish I didn't have to go blog-hopping in order to see what everyone else is saying about this subject."
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.
Anyone with a social life: 'No'.
