I don't find Facebook useful for much and find that it brings the worst out in people, therefore I don't use it.

I do find Google useful but choose to use it very sparingly - no search, no mail, no maps. I do use Drive, Docs, and Photos (for now).

The problem I'm running into is some of Google's services are so exceptional compared to alternatives that it's becoming problematic to use alternatives. Maps is an example of this. In some ways Chrome is an example of this (when considering it as a platform/OS instead of just a browser).

I get the irony that their services are exceptional because of the data they collect, but that's sort of irrelevant.

But at the end of the day, I ask myself how much this matters in the absence of a VPN at home and on mobile when ISPs and cell providers are partnering up with advertisers and government agencies.
