Well, Digg Friend Finder has really made a lot of people happy and has taught us quite a bit about launching SEO/SEM Tools.

Of course it had to go into a top 10 list.....

1: People Don't Read Directions

The ratio of people using the tool to reading the directions is around 15:1. Or vice versa, I couldn't get that right in 5th grade either.

2: Free Products Need Support

Not surprising, but at least the questions are easy to answer.

3: Half the Traffic is SEO

At least judging by the queries. I'm not sure if I expected more or less.

4: Threads Are Confusing

Digg Friend Finder uses our distributed SEO architecture to run the queries against Yahoo and Digg in an Ajax app running in your browser. And because of technical limitations and API functionality we can't really know how many digg friend we can find until a bunch of threaded processes finish running against the digg api. So after you hit "find" it take 10 seconds or two minutes to have the friends come back.

People find this very confusing.

5: Everything is Black Hat

Sigh. No, man, this is about being efficient in your digg friending. It's not black hat - we're within the API, the TOS, and, I wouldn't be ashamed to have my mom find out.

6: NO MAN YOU ARE A #$**&^^%% SPAMMER!!!!!

Well, gee, all caps, I'll take that seriously.

7: Users Click on Ads Even When They're Clumsy

Frankly we did not prioritize ad layout (we stink at that anyway) because we decided that we had other priorities during launch. But a lot of people clicked ads. A lot.

8: People Like Working Tools

We got a fair number of emails saying, in effect, "Thanks for making something that works." Yeah, well, we have a very large list of SEO tools we've looked at and a fair number of them simply don't work reliably. Which is very frustrating.

9: You Can Watch The World Wake Up

If you set the sitemeter geographic display on a refreshing page on Mozilla then you watch people in India, Oz, China and other strange countries (ex: San Francisco!) wake up and bookmark over to your site. Pretty neat.

10: You Learn Something New Every Day

There are 384 posters in digg with HAMSTER and there are 213 with GERBIL. I'd have thought that hamsters were a lot more popular, but then I'd have never thought to look for either. Digg is a biiiiig community.
