Jetpack will cover many of your small business WordPress plugin needs. As of this writing, Jetpack is about a year old and has grown from just a few to fourteen separate features; all are free except VaultPpress.
Jetpack incorporates some of the best Automattic WordPress plugins that used to be available as separate plugins – Sharedaddy, Grunion Contact Forms, Wicket Twitter Widget, After the Deadline, and WP LaTeX.
Several people asked this week how to market a business or charity (or even yourself), if you have no money for advertising and marketing. The short answer is if you don’t have money, you will need to spend time. You will need to take time to build relationships and network and time to follow leads. Ideally you will want to maintain a relationship with acquaintances, clients, and potential clients long term. Social media like Facebook, Twitter, and LinkedIn can help with this.
