Online assistants in far away countries can be useful, but many things have to still be dealt with in the real world. You might need someone to go stand in line, and fill all the forms at some irritating office.
Have a marketplace for local errands. You specify what you need to be done and where, and the system will match you with local people willing to do the job.
Even though you may follow many public figures online, you don’t always keep up with them daily or even weekly.
Enable public figures to allow their fans to follow them geographically, so when they visit a city their local fans get an alert.
You read a book. You think “my friend should read this book”.
You let us know what book you want to buy and to whom to send it to. You pay for the book. The friend who gets it doesn’t know that you sent it. He reads the book. If he likes it he might want to know who you are, so he pays for the book, and we tell him it was you who sent it. When he pays, you get credit for the full amount you paid for your next gifting pleasure. Or if you want to stay anonymous even after he pays he can send you in return a book you might like.
