Help with what? Income or positioning yourself to get another full time job?
You would go a different route depending on the two. For example, you could gain income by mowing
lawns, but it's not likely to help you get a tech job. (although in theory it could via networking) At the same time, blogging is more likely to keep your skills active, but less likely to make money. You need to have a really popular blog for that to happen.
