Yes, you can modify Elgg in any way you want. If you wanna have some functions similar to facebook, browse to the Elgg Community Plugins: http://community.elgg.org/pg/plugins/all/
What exactly do you have in mind?

@abls1,
You can find a customized version of elgg at elggpro.elgghub.com/ to get your site a facebook like style. We also provide customizations as well.
Regards,
Lovegin John
I am also on my way to make the dashboard look more like that of Facebook.
