Re: Bad press & hostility
In answer to your question: "Who stands to gain if Wikipedia slips off into the night?"
Wikipedia badly needs competition. It isn't hard to imagine an open access, free Wikipedia that simply prohibited anonymity (the single biggest cause of grief) and funded some fact-checking. Only ideology prevents Wikipedia doing this tomorrow, even though the quality would improve enormously, and the reach (into schools, for example) would also expand.
Nothing convinces me the world needs another monopoly.
