Yahoo testing the waters for corporate IM: "General-purpose IM clients like Messenger are typically geared toward teens and include features that let users include a variety of smiley face icons in their messages or change the appearance of their client with different 'skins.' These kinds of features are inappropriate in a corporate environment and probably have contributed to the limited acceptance of IM thus far in the enterprise community, where it is seen as something of a distraction." Yes. We must not have smiley faces or personalized design within a corporation! How horribly distracting and unprofessional.
