The best social media starting point for a small business?

[dreamcon]

I saw this question posted in one of my linkedin groups and thought it could be an interesting one for this forum. What would you say is the best social media outlet as a starting point for a small business to launch their social media strategy from?

I would say that it depends on two factors, product and target market. If it is a small business with a product that is targeted at a national market of businesses, Linkedin would be a good place to start as they can seek out and join groups that have the very companies they are targeting as potential clients. If they are targeting consumers in a smaller, regional market then they might want to look at Facebook where you can set up fan pages and advertise to people who are within your target market.
