Thanks Andras & Joachim for the input.  Does anyone knows who is the closest competitor of or alternative to ResearchGate?

For us who are educators, scientists and researchers of this decade, RG is absolutely necessary.  Have a look at this:

" The social webs, available to the researchers’ communities in addition to any other groups of citizens, help the researchers in disseminating their produced or contributed knowledge to global communities. The more you are active in social media, the more you have chances to get noticed by fellow researchers and possible research

collaborators. Many personalized web-based services are now increasingly made available targeting global researchers’ communities, helping them to enhance their social media presence and visibility."

@Fung, I think AE (Academia Edu) is the other alternative site.

Well I really do not know the people that initiated it but it is situated in Germany 

I think all our panel members give their feedback. BTW, it is a good site which helps a lot for all researchers to present their personal view..

Dear Han,

According to the very comprehensive list of Joachim, the Academia.edu, the Linkedln and the Google Scholar may be the most powerful competitors.
