I wrote about reCaptcha before and the big problem with it is that it can be hard. And by hard I mean that the majority of people can't solve it. If you have a big site and you have a spam issue, then by all means, use it. But if you're a small site that's trying to grow and a site that considers every potential user to be precious, stay away from it because the last thing you want is to frustrate people!

Since you will not be a target early on, consider not using captcha at all since spammers don't target sites that have no traffic.

I have to agree with you on that. I only use the captcha when I absolutely need to. What I've found to work well is have the mail go through a good spam filter before you get it.

do you have a link? i love to read your thoughts. I have been thinking about using recaptcha, primarily because of the little refresh button and of course the captcha.

it's somewhere on N.YC but I can't find it anymore :(

comment spammers came to my blog. which has no traffic.
