On a side note, there are a couple of categories that were deemed difficult to narrow. In this case, there were two of them, security and storage. We felt it best to stick with broad skills, such at SSL for security or SAN for storage. Also, within the networking section, it was determined to stick with application protocols, such as HTTP. The remaining categories provided a much easier means to narrow the field to an exact skill. As always, we are open to feedback. Thus, if there is a better way to get more specific results for security or storage, we are all ears.
