i made the cheet format after personally witnessing multiple people i know and/or follow be turned off of this website for the reasons i outlined. it's a tool to help those who feel more comfortable using it. i'm not setting out to "fix" cohost, but help people who are used to Twitter ease into the experience of Cohost.
i do personally think a single line of text - in the title or otherwise - looks a bit sparse on a desktop monitor display, and did tailor the styling according to my own preference. cohost is not the only website where i think that's the case, mind: i think tumblr posts can look a bit Meh when they're a single line of text on a laptop/desktop screen. (i don't think the same when they're on a mobile phone screen though so i think i just have a Desired Width For Reading Things lol)
i spend an equal amount of time on tumblr as i do on twitter so i'm used to short posts both on a platform that does encourage it and a platform that is indifferent to post length. other people aren't as used to that!
i don't believe that Cohost is "lacking functionality" in any regard (although integrating links into cheets does overcome some fringe issues one might encounter with Title Posting, and the more recent addition of pseudo-hashtags is, i concede, 'added functionality'). Cheeter was not, and is not, an attempt to add any missing functionality. i made it very clear on the webpage and in the rationale posted on cohost & in the README that this is supposed to be a semantic distinction. my intention was that one would see a cheet and go "oh, there's a person making a short, throwaway text post. i know immediately that all of this post's content and context is contained within this green bubble".
i think any inadequacy implied to exist in regular, non-cheet short posts is you reading something i have not written and do not believe. i'm entirely indifferent on the matter. i personally don't even particularly feel the need to wrap my own short posts in a cheet format - i've only done so in some of my posts because i worked on the project and am proud of what i achieved (i suck at scripting and enjoyed the process of working on it & being able to exercise my skills LOL)
