* publish anonymously, putting the ideas in the discourse, albeit without them getting the signal boost of one's reputation.
* publish them in a format, such as a book, where you can explain them in such detail that you can ignore people misinterpretations, satisfied that you have explained everything to the best of your ability, and you don't have to worry about people's misinterpretations. This seems a lot of effort, and it's hardly certain one would succeed.
* It's unclear if the problem is that people will misinterpret across the universe of social and traditional media (which seems unsolvable) or simply within a particular forum in which the idea is shared. If it's merely within a particular forum, then one could have a private secretary (or sufficiently advanced AI, or grad student, or friend) cull through the comments for interesting responses, saving you the burden of looking at the rest.
* If, as is hypothesized, the successful are full of ideas that it would be a burden to share, presumably a credible third party could collect and publish these ideas. Politico, for example, had a panel of insiders from both parties who gave their impressions on the presidential campaign, with quotes not being attributed to any particular panelist.
*If misinterpretation comes from people "shooting from the hip" because posting first is rewarded, one partial mitigation might be putting replies in a lockbox and, say, displaying them after 8 hours, with the replies with certain characteristics (longer, more complicated sentence structure, less inflammatory words) being displayed more prominently. At that point more interactive commenter to commenter exchanges could begin.
