Maybe, I guess it really depends on what type of community you are trying to build. Some communities wants a noticible connection between reality and online identies, such as amazon or face book requiring (or at least wanting) real names. Other groups, like myspace or 4chan, don't care what your real name is, which promotes a far different feel of a community.
