Is there any meaningful distinction between liking and upvoting? Also, I think it is very important to signal to users that it's OK to just ignore something. You don't have to voice displeasure, take away a fake internet point, it's perfectly OK to just go on with your day. Twitter especially is not meant for discussions. It's a poor way to have a discussion (because of organization, character limits, etc.). It's also too ephemeral. It's great at microblogging, or just throwing out an idea, or piece of news you want to share, but that doesn't mean it should be the standard of all types of communication! And, for what its worth, I already find relevant replies are at the top. Are they the most relevant? I don't know, nor do I care.
