>I do web development. Maybe I could write more modern text board software that would have the simplicity and anonymity of text boards, but combined with the improved UX and mobile-friendliness of modern tech stacks.
Nobody has ever thought of doing this before.
You claim to be a developer but I find this to be a very curious post. The format of this site is nice in a retro sort of way but clearly it is not what keeps people coming back here. The community and relative activity (compared to someplace like world2chan at time of writing) is what makes this place go. It could be said that a liberal interpretation of the term ``textboards'' are still viable, but for that to be a sound conclusion you would end up stretching textboards to be any sort of forum that doesn't include embedded media.
Considering the proposition of adding value, what could your new software provide that something like reddit or a classic invisionfree-style board don't?
