Exchange Ideas Online

Try the new Alumni Discussion Network

Miss conversing with MIT peers? Join the Alumni Association’s new online Discussion Network and connect with fellow alumni worldwide. Budding entrepreneurs seeking advice, travelers searching for the next great trek, authors promoting their books, or citizens concerned about politics can share ideas, debate, or reminisce.

Join MIT alumni worldwide on the new Discussion Network–wherever you are.

Choose a topic–education and parenting, research and development, pastime passions, and more–and start a thread or contribute to an ongoing discussion. Anyone can view the posts, but only Infinite Connection account holders can contribute their thoughts. Pick a screen name (anonymous or not) and join the discussion.

AI is here.
