Value of sites backlinks web2?

Not sure how to title this. But wanted to get your thoughts on something
Sites like m are these web 2.0 or how do you classify them.
Is it worth it to get backlinks from them? What is the value of these backlinks
I see people charging $50 for each link. Too me thats really not worth it. But wanted to get your thought on the issue.

Are you sure about that ??

Some of them are do-follow and if thrown some tire 2 links they can be use to diversify backlink profile.

There so many web 2.0 at the top these days .

might aswell use a 3rd party service that keep the web 2.0 updated and let you post to them all.

serengine is one of the best for web 2.0

the grate part is scrapebox let them plug stright into the scrapebox app .

this way your always upto date with the best web 2.0

it will cost you monthly, but no stupid price like others are asking like you already pointed out.

by the way , web 2.0 websites are measured via there strength from places like moz and majestic stats .

good luck.

Web 2.0s are still great for link building, just make sure to power them up cause by themselves they don't do much good.

Are the web sites i mention above better or worse then say weebly, tumblr, wordpress etc
Web2.0 where their is no barrier to entry and i can create thousands of weebly accounts etc
