With comments and trackbacks, guestmap and zonkboard, email id and skype handle - it lets me have conversations, make connections and network with people whom i share interests with. And engages me in meaningful dialogues. And i grow, as a result.
With Technorati (the new beta version is pretty cool btw) and Blogstreet, Blogshares and Sitemeter - i allow you into and share with you my reader community.
With blogrolls and by building links into posts, i share with you people who's thoughts i enjoy reading.
With newsreaders and aggregators i discover more about others than i would through 'pleasantries' exchanged through my Ryze guestbook and stars or cubes or hearts as Orkut had.
