well i do curating for steemstem so I am doing the same thing you do. For me, google appears to be a fast indexer (at least for #science) and it does return to me steemit posts as the first result, at least when I am puting the text inside "" , even for posts that are a few minutes old :P

Maybe we should take this elsewhere if you want (e.g. steemit.chat) because we really made a mess of this post's comments XD
