I received a tiny BTC deposit in my wallet recently. I don't know where it came from and I hadn't sent or received to or from my wallet in about 2 weeks before the deposit. Could this be something to be concerned about?

I have received nominal amounts of bitcoin before, but then it disappears again a while later..
I was a bit worried about it when it first happened, then concerned about how someone can send money and it not actually be in my account, I still don't get it, but it seems to be a bitcoin quirk..

That was probably an unconfirmed transaction. Most likely the sender didn't include a transaction fee, so the transaction never got mined and never made it into a block.

It is the Bitcoin equivalent of "spam" so no real need to worry about it (if you are concerned about it being used to *track* some future tx you make then you might want to do some research about "coin control").

How would the deposit be used to track my future transactions? Can't my transactions be tracked just the same with or without the deposit?

What they can do is they can send a small amount to one of your old, empty addresses. One day your client will likely spend these coins in a transaction that involves other addresses you own, revealing some of your other bitcoin addresses. To avoid this you can use the "coin control" feature available in most wallets to prevent the tracked address being used in the same transaction as your other addresses.
