The lonely pretty girl syndrome and invite-only websites (eduardo.intermeta.com.br)

Couldn't agree more, this is also why doing some capacity planning before your post it to hn or slashdot or whatever is a great idea. The first thing I do on an invite only website is say "oh cool, I cant use this." The second thing I do is anything else because I am not coming back to that website. Same goes for products rendered inoperable by the traffic slam, I know it sucks, but if there is nothing to try to keep me, you need to have the best idea ever for me to visit your page ever again(and I still probably wont).

I can't guess how many web apps have lost me because, instead of signing up right then and there, they waited a few weeks to put a beta link in my mailbox. By then, I'd moved on.

You don't sell anything by telling your customers to come back at an indeterminate time later. I'm here now, so let me give you my attention (and possibly money).

tl;dr DN is really HN with a better interface, but the same type of comments you'd read here and a similar format.
