As a SharePoint SME, I tend to get odd looks sometimes from people who clearly have no idea of all that is involved in the technology, let alone being a subject matter expert. Most people think it's point and click and I have to say, that drives me batty. I'm not sure what fosters this perception, but it's out there. Joel Oleson has an excellent blog post that lists a pretty good set of skills that we are are required to have extensive knowledge of to be good at what we do. His list does not include any dev skills, so go ahead and add those in for an even more well rounded SME.
Joel's list is here.
Now no more funny looks, ok?
