I was curious to see how Synthzone is represented in Alexa, a web analysis site.

Along with charts showing a surge in hits recently (probably due to the recent Tyros mania), they have the following description:

About Synth Zone (synthzone.com): A directory that covers synthesizers and midi controllers, plus relevant music software and support products.

Synthzone.com is ranked #104,158 in the world according to the three-month Alexa traffic rankings. Approximately 70% of visits to the site are bounces (one pageview only). Compared with internet averages, it appeals more to men; its audience also tends to consist of childless people browsing from school and home who have no postgraduate education. This site is located in the US. Synthzone.com has a relatively good traffic rank in the city of Greenville-Spartenburg (#8,578).

18-24 year olds? where?

I don't know for sure if those analytics are taking the forum into account or just the site.
