A new start up pattern is emerging overnight in the content space. First you form a team, then you get a little funding, put out a beta site and generate some buzz. Then, naturally, you change your name. Within days of each other we had news that community and guide content player Vailoma is now called TripSay (announcement) and content/review aggregaor Kango is now called UpTake (announcement). Could be a strong sign that finding a good URL and a name that means anything is now near impossible. That it is faster to get the product out than it is to secure the rights to or think up a decent URL. In Kango's case it is also because of the confusion they were experiencing with auction ad meta-tool Kaango.
A did a little piece here that involved these two players if you want some more background.
