You can infer quite a bit about people's unwritten intent. How?
- When a person's cadence changes from their normal cadence when they interact with you - whether slower or faster
- When a person ignores a directed update on their Wall or in their Twitter stream
- When a person does not follow another back or friend them
- How and when someone inserts themselves into a public conversation
- How a person proactively requests connections and on which platforms.
- What and who a person RTs or shares
- How reactive and emotional individuals are (are they quick to judge or slower to respond to good/bad news?)
