There has never been a strategy to "compete" in our mind; our objective is to create an app that is truly useful, stable and always-evolving, regardless of who else is in the market. By staying focused on creating a great product full of useful features, rather than playing a game of tit-for-tat with a competitor, I think we've built a better product and have a happier community of users.
This issue about competitiveness has always intrigued me. Professionals that have their focus on their "enemies" lose sight of their customers and their product’s quality. At least, this is what I typically notice.
People motivated by competition often have a sourness about them. In the long run, it focuses their energy on the bottom dollar. If they dwell on their shortcomings they evetually resent the market itself, and they flaunt an undeserved self-respect if they are too aware of their success. ∞
