We just started telling people about the site two days back via Facebook/StumbleUpon and I guess HN now, and we have just above 40 signups so far. Conversion is pretty low, but that's expected without any real content. Need to fix that, add the demo perhaps. Part of asking what stuff people are into is to try to find a recurring theme, so I totally agree about that. I think your comments about hackers are on target mostly, but I don't mind the criticism. It's really better than having friends tell you how great what you made is. The logo was not worked on too much, and I'm not exactly good with graphic design. I'm definitely going to get a professional to redo it in the future. I'm not sure it would make a huge difference to whether people sign up for beta, but I can see how it might.
