Best ways to get your site noticed ?

Can anyone recommend any good/cheap ways to get a site noticed ?

- Signatures on forums ;)
- Search Engines (here's a nice link with a bunch of info and a ton of free tools)
- Link exchange (Link Market)
- Classifieds

...

And do not forget the good old "grapevine" or "bush telegraph"..............like in word of mouth.

If you have a good site and you mention it to "opinion leaders", they will pass it on.

Just like people recommend software on this site...............or people recommend tradesmen or suppliers.

Just a thought
