Which “plugins” WordPress.com uses (natively)

No, this is not yet another question on how I can use plugins on my WordPress.com account. ??
I’ve done some search on the forum… wow, so many questions like that.

I just migrated from WordPress.com to a self hosted account, and I wanted to know if there’s a comprehensive list of plugins I can get to make a “perfect” copy of my WordPress.com account.

I only know of two ’till now: Askismet and Stats.
I’m aware WordPress.com uses WordPress MU instead of the standard WordPress soft provided by www.remarpro.com

Didn’t know in which forum to post this question, so I posted in both… I guess it’s a question that involves both systems.
If I did a mistake, please forgive me.

Thanks for your attention!
