What are Twitter pitch fests?
Twitter pitch fests are limited periods of time (usually one day) during which you can post a 280-character pitch for your book.
Agents are on the alert at these times, and they have the option of “liking” your pitch, and then asking for a full or partial.
If you have a completed, agent-ready manuscript, tweet your pitch! It can’t do you any harm, and it doesn’t preclude querying agents.
Believe it or not, pitch fests actually do work. Busy agents are often more likely to read and respond to an interesting twitter pitch than they are to a query. It takes less time and a lot less effort.
