Why would I do that? I'm not a domain expert in chat apps, and I've already got my own projects and software to fix. If I'm going to take on the maintenance of some chat app, why wouldn't I just build the whole ass thing myself from the beginning? Or, more prudently, why wouldn't I just skip over this one and find a chat app that's got a track record of continuing support so I don't give myself a headache down the road?
