For now only one modder has posted 3 mods (very interesting ones, hehe), but I encourage you to use that site because its optimal way to display mods, every one with its personal forum and well ranked to easy find the most useful.
Excellent news! I love the Nexus site. I hope everybody posts their mods on it. But I've a horrible suspicion that the majority of mods are going to end up on that Steam abomination (which I refuse to use).
