Well yes, we all reinvent the wheel all the time in C++ It's something the Java or the C# guys don't have to do but sadly we have to because the standard library is simply lacking. For instance, how many custom String classes are out there? hundreds! but who can blame them if std::string doesnt even have a trim() method! So, as long as we dont have a standard wheel that's good enough, we will keep seeing the wheel getting reinvented over and over again.

AFAIK, most of the functionality is still covered by ACE. What is the main difference then?
