Tell me a story in 140 characters or less.
That can be a monumental task and it can also be fun. How about a link to photos or music or an article. 140 characters can be pretty entertaining. Your blog has to create your brand story. Make it interesting, make it compelling. Make people want to come back again and again to see how it all turns out. Relate to your audience. It may take time to find that spot that everyone loves but that is part of the adventure.
