If 500 people subscribe to the DomainToad newsletter by April 1, 2011.
Oh look, a catch! Shocking!
Why would I do that? Because I spent a fair amount of time and some money to create the website and I would like to see that people at least try it. Releasing the code publicly will also take some more of my time to clean it up a bit and package it. If nobody cares enough or finds it useful enough to use, then I won't bother spending my time to release it to everyone for free.
I've released a lot of software I've written over the years for free or provided access to them publicly for free. Most probably never got used by anyone but me, if people are genuinely interested in having a copy of the code I wrote for Domain Toad they will subscribe for the newsletter and get their friends to subscribe as well. It's free and provides headlines from major domain blogs in your email daily. Other websites charge for that 'luxury.'
If the newsletter gets 500 subscribers before April 1, 2011 I will release the code with the open source MIT license. How will people be notified? I will post on my blog and email the newsletter subscribers a notice if it has 500 subscribers by April 1, 2011.
If someone is really that desperate to buy it, I will sell copies for $250 as is with 1 hour of support to get started with a non-exclusive license to use/modify it but not distribute unless it becomes open source. Contact me.
