Last week a freelancer who writes for a big newspaper contacted me on a subject I couldn't even help him with - but he found me on the web. I had written a piece on moving. This week it was a freelancer who writes for money magazine, writing a piece on careers.
If you write articles, and submit them on the web, that's what happens. That career piece? I wrote in 2000 and posted it on the web that year or the next.
Ya just never know who will read your articles and when!
