My first task when I reach the homepage is to learn about your product. The only two options I see initially are to View Plans or Try It for Free. The only info I get about your product are a few unexplained screenshots and some content-free bullet points. Tell me a story. Show me how I and my users would use your product. Show me why your product is "awesome", and why it's better than any of the other 357 bug tracke…
Why not explain a little more.. furthermore I would limit the choices between View plans and Try for Free. People don't want to be reminded to out shell out money and work better with fewer options. It is hard to imagine early case scenario of people skiping straight to the paid plans, let alone using it in the first place right? The first priority is building the user base i'd say put the view plans button in the navigation or somewhere else and just have a big fat "try it!" button. If people are interested and like your product they can Evangeline and actually go to a paid plan.
So them why! (I think you can incorporate the plan selection in the "try it" process also if you must have it there. But make it a little more inviting!)
