As a web developer, it's been great not having to worry about supporting/testing with Opera's rendering engine, (or simply another rendering engine, nothing against Opera in particular) thanks to its low market share. I hope this doesn't mean I have to start testing with yet another browser. Can't FB use Webkit like everyone else?
Having around three-four rendering engines on the market is a good thing, they each separately fuel development of new standards and other projects. We don't want Webkit to become the new IE6.
How does FB buying Opera change the number of rendering engines on the market? As a user, I wouldn't touch FB Opera with a 10-foot pole, but I do at least consider using Opera as the product of an independent company.

If you're not testing in more than 2-3 browsers, I seriously have to question your acumen as a "web developer". Browsers do exist outside of the Webkit bubble.
