I see. Sort of like the preview function for websites in a Google search?
Well...maybe. It would make replying a bit more convenient in some cases, however...
many ppl. have no bio,
many ppl. have a relevant introductory post,
quite some people have long and group-specific slang lingo in their bios.
When I reply to touchy subjects, I try not just to screen the bio but also power-read some pertinent posts, to get a better impression.
IDK.
