Examples of successful .net or .co sites?

Question

Marketing

I'm doing research, and it became curious to find the top domains in these zones.
Offhand, I know only 2 top sites on .net - Slideshare and Behance
I don’t even remember anything on .co ...
And which ones do you know?
What are the tools, ratings to conduct such a research?
