Report says "Search giant Yahoo has opened the source code for its e-mail service to open source developers, according to this piece. The move is an effort to encourage new e-mail-based applications, and it can't hurt the company's buzz, either. Giving customers input into the product, a Yahoo rep says here, could result in tens of thousands of Yahoo Mail-based applications. The company may be big, but it can't create every single thing its users think they might need, he says. Though the company plans to maintain the secrecy of the code behind user names and passwords, practically everything else will be accessible."
