Whatever. URL shortening in and off itself is easy. TinyURL had nothing stolen from them. The only thing that mattered about bit.lky was those extra features.

Have you ever heard how bitly works? It is really "over engineered" on purpose to be in a completely different category from other shorteners.

Such is disruption. TinyURL hasn't changed in years unfortunately. Total lack of innovation after they lucked into that first swipe of goodness.
