Whose success and accomplishments? Why would a researcher be jealous about some website getting many visitors? Maybe I'm misunderstanding your point.

Given the state of the situation, a wiki-style site for information sharing is just not going to happen. Nobody, authors first, has the interest for something like that to happen - researchers are very interested in sharing, with other researchers. The general public doesn't interest them one bit (you can show the number of citations your paper nobody read has received to have your grant renewed or to get a better position, nobody cares if you've built a website that shares your research with the general public and has 10000+ uniques a day)
