I find it useful to approach a group of people talking and just start actively listening to whoever is speaking. People often look for support from the group they are talking to. Nod in agreement when they do. Ask an insightful question. Make it easier for them to be the center of attention. Soon you'll be in a conversation without having to introduce yourself first. As soon as you are in a 1 on 1 conversation, be sure that you do introduce yourself. It should be a lot easier by then.
