[0] Plugins and PHP-hacking [WordPress.COM] You can’t use plugins, though widgets do offer some of the same functionality. If there are specific things you want to do with your blog, check if WP.com will offer them.
You can install as many plugins as you like, and even change the core PHP code of your blog. It’s yours to do with as you like.
