Send a DM (direct message) to someone on Twitter who follows you, but with whom you had not had a lot of direct interaction. Or use email. Maybe refer to a person in a Google Plus post. Ask him/her an interesting or thought-provoking question. Spark a conversation.

Today, we suggest you go visual with your connect and pay tribute to a fellow connector. Find another blogger, or someone with affiliated views, and pop a intriguing blog post into a Word Cloud Generator, such as Tagxedo, Word It Out or Wordle. Share out the Word Cloud and make sure to acknowledge the blogger (and let them know you were visually inspired by their verbal thoughts). Post the cloud to Twitter or in your own domain.
For example, see @koutropoulos and what happens to his interesting post about Network Fluency.
