With tips, the nice thing is that you don't necessarily need to have a shop. a blog for instance or any other website is sufficient. You can display QR-code or just your Bitcoin address at the bpttpm pf your page or wherever it seems convenient and let people dicide how much they want to tip you. You can also wiew hoe this looks like in the footer of this German Blog bitcoins21.
Another really cool way to get tipped online is ChangeTip. this service allows you tı integrate tips on all major social networks, Youtube and github. Very nice!
Imagine you have a resturant and want to encourage your customers to tip with Bitcoins, there is this nice service: btcip is a website where you can print little paper voucher that have a certain Bitcoin balance on them.
