Finding a parking space near your train station or place of work is difficult to start with, finding a cheap one is nigh on impossible. So, someone made ParkatmyHouse.com. Seems like a great idea. They take 10% of the rent, but that seems reasonable!

If one of your New Years resolutions was to do more reading, Daily Lit might be a site you should visit. They have a bunch of books to choose from and the innovative thing about this is that you get to read them in bitesize sections via emails, scheduled to arrive in your inbox, say, at 9am every weekday if you want. What a great idea!
