This is interesting. Part of the beta sign up asks you what OS and database you intend to run HelpSpot on. Here are the results so far:

OS:
*nix: 34
OSX: 6
Win: 20

Database:
MySQL: 46
MS SQL Server: 12
PostgreSQL: 2

What's most shocking to you?

For me on the OS side it's the high number of Windows users. This is actually very encouraging to me. While PHP is probably the most widely used open source language on Windows it was still a concern I had that Windows users wouldn't be interested in running it in their businesses.

For the databases, it's the low number for PostgreSQL and the relatively high number of SQL Server. Come on PostgreSQL people let's spread the word we need more beta testers than that!
