I just got a copy of Google Sniper 2.0 by George Brown. If you've never heard of him, he came up with a system to create niche websites, drive massive traffic to these sites, and, as a result, make money from affiliate commissions and ads. That system was the original Google Sniper, which he launched a year or two ago.
For a couple of hours earlier today, I couldn't get online using my browsers (Mozilla Firefox and Microsoft Internet Explorer). My instant messaging applications were working fine though, so I suspected that the issue was probably a different port or protocol.
