Nasal, there's a list of what bloggers get out of it on the 'about us' page of the network.
Anyway, from a personal perspective, it's the ability to generate new readers and regular hits - you're getting a wider audience, and some support along with it.
It's only worth joining if you want people to read your blog. If you're blogging for purely personal reasons, then there's probably not that much point. But if you want as many people as possible to be exposed to what you're writing, then joining blogger networks can help.
It involves filling out the registration form and putting the badge on your blog, and that's it.
I think FlamingoBingo has explained it perfectly! I blog, but not on here...currently have 3 on the go. Not many readers though but that's fine - it's just a way of ranting/rationalising/showing off for me!
Ok don't think I'll bother then. Shame because I used to enjoy joining in the blogging threads but as theyre now all on here. I don't want mn connected to my blog though as I have a few people who follow me a bit too much if you get my drift
My normal name and my blog are too closely related (. i'm going to be changing back soon) It does say above that its not for talking about other blogs. When I say not wanting them linked because of being followed its more coming from my blog to here rather than the other way around (Mum!- she does already on fb) once here it would be quite easy to establish who I am anyway. i've posted my blog on mn a few times before (pretty sure you would recognise it Mme)
