I am a software developer and @resteembot is simply one of my projects. I will simply move on to the next projects. Maybe it will be a bigger and better one.
Also - I might be a decent developer, but I'm sure there can be better people for the bot. People that will not just maintain it, but expand on top of it. I would not do that anymore, because I'm starting to shift my focus to bigger stuff. The bot is kind of dead if it stays with me.
