I've Joined the Balsamiq Mockups Bandwagon
I thought that Balsamiq Mockups might not live up to the hype but after using it for about 45 minutes and clearing many tasks out of my backlog in the process I've decided to become a fanboy too. The principle behind it is that it's a mockup tool and it does that well. After a while I started thinking that it would be nice if there were templates or some sort of folder structure so that I could really build a prototype but if you add all of those things it loses the beautiful simplicity that makes it so great! I like the fact that as a company they are striving to keep it focused and not let feature creep destroy this wonderful product.
We are trying to do the same with Zingzam so hopefully when you come across something that you feel is missing we have a good reason for not including it. Of course, it could be that it's in the backlog and will be added soon but that doesn't sound as sophisticated, does it?
