So I know my own opinion as to the "most promising" alt coin other than Bitcoin, but I'm curious what the popular opinion is for this topic. 

I will wait until 50 or so votes before saying which one I believe is the "most promising" and why, so that I can at least see what the unbiased vote result is.  I will also announce the "in progress" vote count as I write my viewpoint. 

Of course, anybody may post in this thread at any time to try and influence the vote count!
