Apropos character limits: maybe you could stop counting (2001) etc. towards the 80 character limit in submissions?
Because a few times I have left out the year since I couldn't find a good shorter title, and then you added the year afterwards. I would have done that myself. :-)
Submitters: please do not rewrite titles unless they are misleading or linkbait: https://news.ycombinator.com/newsguidelines.html
Please especially don't rewrite them to make them more misleading and linkbait. (Submitted title was "Twitter ditches 140 character limit".)
