Best web 2.0

hi there

can someone tell me which are the best web 2.0's site where you can post your article on the root domain and not on the subdomain?

I'm interested for a site.com/myarticle and not for mysite.site.com/myarticle

Also the link should be ********.

I'm thinking something similar to medium.com (the article is nofollow there)

I'm gonna post original content so it doesn't really matter if it's auto approve or not. We can skip buzzfeed now since it's harder to post there nowadays.

Please don't post old lists with web 2.0s and post only if you know some good ones.

Op those are really hard to find. I doubt people are going to share them, as they work really well for churn burn projects.
