travelin cat, congragulations on making the best choice and wish you all success in your new google independent business model on the web.
But I qualify the words "free traffic" with double quotes because nothing is free. Webmasters allow them (Google) to crawl and index their websites as they send traffic and google crawls and indexes their websites as they had to serve their users who make them money. Though there wasn't any binding relationship between the two parties, there isn't anything free in this arrangement. Webmasters bartered content for traffic that google sent their way.
In this kind of barter economy, Google decides now and then to dump certain websites and their owners in favor of others.They could do that because they have established this kind of economy on a massive scale on the web and they aren't dependent on any individual webmaster or groups of webmasters. They source their content from diverse suppliers and that makes them immune to these outcries from a subset of webmasters (who aren't popular).
Yours is a perfect example of what webmaster should do going forward. They shouldn't be too dependent on one source of traffic.
But there is nothing free in this barter economy and I am guessing that this is just your way of saying goodbye to them and not necessarily to thank them.
Swapping is the increasingly prevalent informal bartering system in which participants in Internet communities trade items of comparable value on a trust basis using the Internet. The most notable disadvantage to electronic barter is inherent in Internet commerce, that of trust. How can consumers have confidence that they will receive what they bargained, or paid, for? Although the Internet based consumer market has by its continued existence and growth demonstrated that it works, there is never a guarantee of satisfaction in consumer to consumer transactions. There is no absolute defense against fraud. However, it can be argued that when a person barters there is less incentive to deliberately mislead. Neither party is paid; each party receives something that would only then have to be converted to cash
