I think I found a solution that would satisfy me and my collegues.

The company has a HUB website, sort of a community site where they post all the internal announcments etc. There is an option to create your own small blog. I think that would help in some way to pass my knowlage to people in the company that want to know more about SQL and how it applies to our machinery and on the other side it would help me to open up a little bit and show my creative side.

Any suggestions, opinions?
