if the majority used Bing.. we'd be fine!
In the short term I have to agree (and as already reported my own logs show signs that there is some user drift in that direction, although it is slight).
However, I don't think we can assume that any search engine will forever keep pace with the massive growth in data, or that the problems Google is trying to fix will never affect Bing.
Part of the difficulty is that both Google's algorithms and consumer searching behaviour evolve interactively.
The current penalties seem to affect a lot of people that previously enjoyed favour (not just posters here: as I trawl through to my current page 46 position, I notice that at least half of the sites that used to be vying with me for the top space on page 1 are on e.g page 38 now).
To me - and probably to most searchers - the current favourites are less relevant (and arguably spammier) than the old guard, but it is fairly obvious that what was given priority in SERPS has changed. Two things I guarantee:
1. It will not change back to how it was before;
2. It will change again.
The best strategy, if Google SERPS are vital, is to try to understand and move with the current evolutionary trend.
However, I didn't give Google any thought at all in deciding what sort of business to be in: Google has just been one (major and successful) marketing tool until now. Getting obsessed with Google - I recognise I am as obsessed as most of the posters here - is in many respects taking my eye off the ball. All businesses need successful marketing to survive, but marketing isn't why we are here, or what makes a good business.
