There is nothing wrong in being a "me too" clone. In the early stages of a market (in any business), when someone stumbles upon something new/novel/untapped, there is always a land-grab and (initially) often plenty of users for everyone. Ultimately success really comes down to the offering provided (e.g. you offer same service but USP being simpler GUI that saves you time) and the ability to iterate quickly and develop features that users want and find value (ideally without adding unnecessary complexity to what you already offer). Many a successful company started as a "me too" clone (or late entrant), later becoming the dominant player. It is only when the market is saturated do other issues such as "churn" etc. (e.g. as seen in the established mobile-phone markets) start coming into play. Now entering the market is actually not a good idea, unless you are offering something radically different (ideally a disruptive technology), but then you would not be a "me too" clone.
