Instead of editing the title, the guidelines have this to say:

> Otherwise please use the original title, unless it is misleading or linkbait; don't editorialize.

Edited titles (without a reason, like abbreviating them to fit or removing elements suggested by the guidelines for elimination) just get reverted, you're creating work for the mods by not submitting the original title.
