I had to start thinking about Jetcareers as a business and formed an LLC or "limited liability company"
Primarily because it's extraordinarily expensive maintaining a website with the traffic that it's grown to. In the earlier days back in 1996, I got away with using my 3Mb of webspace as part of my mindspring account.
Then I went to a small shared hosting plan in 2000. Had to upgrade it later that year. Upgraded again in 2001 because of growth, and then had to upgrade it again in 2002.
Traffic took off again in 2003 so I had to upgrade my service to the highest/most reliable plan, but it couldn't keep up with bandwidth so it was either get kicked off the server or lease a managed, dedicated server.
Not too cheap, but considering the fact that I was paying pretty big hosting fees on top of $80 to $150 in monthly bandwidth overages on a regular basis, I needed the bandwidth and capacity of a dedicated server.
So the banner advertising, consistent with the 'morals' of the website, have worked well in helping cover the costs of the website. Whew!
