I think by anonymous the op means he is planning to create a bitcoin exchange where you dont have to give your valuable informations such as email id etc. Now most of the exchanges require your full details for buying or selling the bitcoins for fiat currency. Bitcoins are anonymous but you have to provide the exchange your full details and you have to submit your ID for verificaion check. So the point of anonymous doesnt have any value here. The op is planning to build a exchange where it doesnt have any signups or verification checks to keep the buyer and seller of bitcoin anonymous. We need more exchanges like that.Its a good project and all the best for his new project.
