Smashing Mag tweeted about SnipSave as a useful tool for web developers, which led to thousands of visits in a short amount of time and about 370 new signups, the first real wave of new users.
The following couple of months saw higher than average signups, albeit much lower than the initial surge. Then things died down for a few years as I moved on to other projects.
I didn't update SnipSave again until June 2015.
