I've looked it up, done tests, etc. I'm not getting the results/answers I'm looking for. I'm playing on this server where the only hostile mob that spawns in my area are skeletons. I figured I'd make a simple mob grinder, and I have it all set up and built now. I noticed that in some mob grinder styles, no signs are needed and the mobs seem to just magically fall into the water without anything pushing them, scaring/attracting them, etc. They just seem to walk right of the edge, even though there are no signs, tricks, etc (is it because so many of them spawn that they push each other off the platform?). My mob grinder is structured slightly different from others, but that shouldn't affect it. For some reason though, the skeletons don't just walk right off the edge. Even when I placed some signs to test it, that didn't seem to work. There is flowing water below too. Am I doing something wrong? If not, any suggestions on how to push them towards the edge? (I don't have much space for redstone, so pistons/dispensers are a last resort.

I'm assuming you're not talking about a grinder that uses a spawner from a dungeon. If you can make a grinder using a spawner from a dungeon instead, do that. It's a lot more efficient for a lot less work. But if for some reason, you can't use a spawner:
First you have to light up every cave and the whole surface for a huge distance around it, or build it high enough in the air that you can stand so far away from the mobs on and below the ground that they despawn. The first option is a ton of work, and the second one is less efficient. I'm assuming you've already done one of those two options, since you're actually seeing things spawn. Then you have to deal with spiders somehow, except from what you're saying, they aren't spawning, so I guess that's not an issue with you.
How far is the drop from the spawn area to the water? They might not be wandering off the edge because it's too far of a drop.
Also, even if you don't have the resources to do a full blown piston pusher design, you should at least be able to muster enough materials to make a simple flooding system on a clock. Basically, every so often it pulls back a block that allows water to flow in and push them off the spawning platform, then closes it again to dry up the spawning platform, allowing them to start spawning again.
the drop to the water should be no more than about 11 blocks. I've thought about doing some sort of water pushing system, but I'm working with a lack of space. I will use that method if I find no other though. Thanks Sargos for your response.
That's likely your problem, if I remember correctly there's a maximum distance that any given mob will fall. They won't intentionally take fall damage, and don't check for water at the bottom, so it seems to them that they are walking straight off a drop.

Ok, thanks. Do you know what the maximum height is by any chance? I might have to do a lot of testing in single player.
Mobs will not willingly walk off a ledge that is induces a fall that results in fall damage. They will jump down all day long if the drop is only 3 blocks high, but 4+ and you have to use AI tricks to make them think the block they walk to is solid (ie, a trapdoor).

I did some testing. It seems like they willing fall into water that is flowing 3 or 4 blocks below them (depending on how you count). Thanks everyone!
