Sorry for the crazy subject but yesterday I had a chat with some foreign students in Hangzhou, China. Most of them had heard about skritter but did not try it out due to the simple fact that even a free account requires you to sign up with a credit card. I know this have been brought up before but you really should think about this strategy. Especially non US potential customers are very reluctant to sign up for anything free if you need to use your card. Many do not even have a card. I know for sure that I would not have signed up if it had required my card back then and I am now one of your most loyal customers:-). I am rather sure that you miss a large part of the market by having it this way. Other ideas that did pop up from those individuals are possibilities to buy packages. Let's say a semester package with a discount. Me my self would love to have an life time package to buy. I like to buy large packages instead of monthly small payments. Think I have a three year now with Cpod. Word of mouth is a very good way to bring in new customers and most of the people I talk to are very eager to use it but those small things stops them sometimes to actually start using this. Just hoping for more fun customers to Skritter:-)
