I would highly recommend starting a blog if you have something you find interesting to say! Or even of you want to demonstrate the message that your company wants to show. I started my blog worldofindie.co.uk purely because I saw other companies posting about what they found interesting, and the comments being full of other cool information taught me so much. I like to post about what I am up to, and write things I would want to read. You may not get much traction at first, but it is sometimes useful to step back and write about stuff in a different way to everyday engineering writing. Basically, go for it.
