well, communication might be a barrier. Even with Good communication, we[site admins] repair few minor bugs ourselves and "never report to boonex".
reason is we dont have time to do that because we pay to buy a cms, pay to buy mods, pay for the server, pay incentives to members, burn our time/head to do something better day by day. thats it.

say, Boonex has 1million registered and premium accounts.
when the site encounters an error, i get an email. if the same email is cc'd to some see more bug analysis system in boonex. the boonex members,developers,experts can watch that and do major bug fixes. which will make the platform more stable.
Eg: firefox crash report, Windows Error Reporting...

this is heck of a job which needs too much manpower. still if the top 10 bugs are killed thats better than the rest.

i'd be happy to pay $$$ to hook my server with boonex to ensure that my server is monitored by boonex for stability issues...
