How NOT to sell software - JetBrains web site problems
JetBrains is currently running a special promotion for Resharper, offering a "Personal License" to individuals for $99. Being potentially interested, I've spent the last couple of days trying to get an eval license so I could try the software before buying. Unfortunately, filling out the form for a 30 day eval license and submitting it just results in the error ""Our server is temporarily busy. Please, try again later or contact us via e-mail: webmaster@jetbrains.com". I sent an email to that address, but got no response. This does not make me feel warm and fuzzy about buying their software.
This also highlights what I think is a silly but not uncommon practice - the timed-limited license key. If you want to enforce a time-limited eval, great. But don't make me request a special key in order to evaluate the software - just start the clock when I install it. You goal as a software vendor is to make it as easy as possible for me to try (and hopefully get hooked on) your software. The more barriers you put up to that, the less like I am to try it, and the less likely I am to buy it. The "request a key" approach is both an additional hassle for me and introduces a potential point of failure - as in JetBrains' case.
