The last several times I have attempted to chat with a random bot, I have been unable to get any response other than "Hi (username)!" I think this is due to too many 'starter' bots that don't even have basic communication capabilities. To be quite blunt about it, if people can't see these bots in action, they aren't likely to become interested in the project. It might be worthwhile to consider some sort of filter, so that at the very least, guests may begin chatting with functional bots. I hope this isn't taken as harsh criticism, as I've been very excited about these projects since finding out about them (the link is right at the top of my browserbar), and I am always eager to explore the capabilities of these programs. I think that easy-to-access experience is important to bringing in new users and contributors.
