The best thing about a LL is that when it is finally making a profit (which can take 2 years) it is something worthwhile and can be built more after that - the worst thing is it usually takes a good 2 years to see a steady income.
If you are just looking for something to run your free site traffic to - definitely agree with the others - a hub is the best way to go - of course a hub can become a LL eventually
