So should users like me (who are personally not bothered about anonymity) follow different recommendations and use Tor for as much normal activity as possible, to make it easier for others to hide?
Just by using the network you're increasing the size of its user-base and making the crowd in which other users can hide that little bit bigger.
One thing you shouldn't do is make yourself stand out from the crowd in any way. By standing out you differentiate yourself from the others, and thereby don't add to the identical, anonymous crowd.

One way to test the level of uniqueness in your browser is by using Panopticlick.
