It does seem quite logical to expand Steem as a cryptocurrency it really needs more real world places to accept it as payment - you can convert it to another crypto and eventually maybe get some physical money through that - but the fees and hoops are often too off putting.
I know of @steemgigs but have not had chance to look into it yet, I believe it is basically Steemians offering to do various tasks in return for Steem. I'm interested to look into @steemtipper I have not heard of that and it sounds like an awesome idea.
