Hmm, this is a really great product and I've loved using it, but 2 projects? That's so ridiculously low that 'free forever' seems a bit hollow and vacuous now. It would be better if you just came out and said it. Are you just supposed to go one humungo project now?<p>I'm certainly not paying a monthly recurring fee for a mock up tool to play with side projects! I could see upgrading it for the collaboration aspect for clients, but for toy and hobby projects you've seemingly just killed the tool.<p>Calling it 'using in a casual manner' is bad, how is having a project per idea and being limited to 2 ideas 'casual'? A helpful compromise?!?<p>Personally I think you've focused on <i>completely</i> the wrong thing to go premium for. I'm surprised you didn't go private projects & apps/dropbox integration (standard) > revision control & master pages (pro) > collaboration (ultimate) or something like that. But that's just the programmer in me I guess, we all know that multiple projects won't add to your costs, just massive inconvenience to the free users.<p>Still, it's your product so do what you want and you're allowed to change your mind, just don't expect a lot of people cheering you on. I'm just personally sad I probably won't use it any more as I'm not going to faff around trying to organise multiple thoughts into one humongous project.<p>As a reminder of what you originally said when you introduced it to HN:<p><i>We'll keep the main functionality free (with some reasonable limitations). We plan on adding some really cool collaboration and annotation/feedback features soon that we'll probably ask a buck or two for.</i><p>I just don't see 2 projects as reasonable at all but I always suspected something like this would happen as the tool was just too well done. Note that I would probably buy it for a reasonable fixed price (like $50-70) but obviously the storage, etc. will constantly be a drain on you. It is better than balsamiq, but not better enough to be dipping into my pocket every month for the rest of my life. The problem with saas I guess.<p>EDIT: I guess this is the problem with an online tool being useful to both individuals and corporations. I can see real value from a recurring fee from dropbox as an individual, but a mock up tool? For what (should) be a desktop app that's gone to a sass model, are individuals really going to pay a recurring fee for this? On the other hand, it's a perfectly reasonable price for businesses, even small and micro ones if you use it regularly. I would definitely sign up if I do more consultancy again. Perhaps I'm cheap as an individual, but to me it's just far too expensive for my personal use case.
