I like how it connects people in ways they wouldn't otherwise, so when you visit someone's blog/website or post something yourself using flatter (or get one of your friends!), there are little widgets where other readers can click through as well! It also helps me out by giving my posts more exposure than if only myself had posted them. Sometimes clicking doesn't work though for whatever reason -- don't know why but just try again later sometimes :) Also would be nice if we could see what each person has given us. But overall great service!! We have been able to increase our traffic because this site lets visitors give money instead of buying ads which costs lots of cash every month. They've helped boost revenue too. This isn't free either btw - some credit card companies require an annual fee at first before allowing any transactions. And yes you do need funds up front- not ideal. The benefits outweighing downs.
