In over a year, not a single person has downvoted either this question or the only posted answer (which agrees with OP's position that the text should be "grammaticised").
So I'm posting my answer because I like the current style. If anyone else agrees, they can upvote it.
I started my previous paragraph with the word "So", which was perfectly valid in context. But practically every other day here on ELU we get a question starting with "so" (often not capitalised), where the word doesn't (and can't) relate to anything previously mentioned.
I do think that's taking "relaxed informality" a bit far, so I sometimes edit out the offending word. But the default title text strikes just about the right level with me and/so I'm quite happy with it.
