Nope...still haven't gotten even half of them, probably never will.

And why will you never get them all? Because nothing is shown on your map. The pigeons that you already got are not shown. And even if you got 95% of them, you will never be able to know where the last few are. UNLESS you strike them off a fucking guide, which is tedious and shouldn't be needed at all.
Finding a Pigeon that barely does anything in GTA4 is far more satisfying than looking at my map to locate/activate a shrine that boosts my health in Sleeping Dogs.
Uhh, you didn't understand. The collectables aren't shown right from the start. They are shown, if you accomplish certain tasks. Which means you are free to explore (and should do that) during the game. BUT they show them at a later stage of the game to help you finding the last few ones. That's quite helpful for completionists like me. You are obviously not a completionist, so you shouldn't even care about this feature. It also seems that you obviously also have not even played the game at all.
BUT because of this feature I was totally FREE TO EXPLORE the whole game without a fucking guide, BECAUSE I knew, that if I miss a few, it won't matter, BECAUSE I will be able to see their location at a later stage. I mean I tried this in GTA:SA and was then missing a few of this and that and whatever and had to restart the whole fricking game and then use a guide for every single one. Isn't that fun? No, it isn't. Finding every single one is just not possible without a guide, because you don't even know the ones that you got, because you already picked them up. Uh, that's another point. Cameras, lockboxes, health shrines all STAY there, which means even without the map, you would at least know that you opened/hacked/got them already.
