This query shows that a significant proportion (7% or 12.5K answers in the last 12 months alone) of answers to SQL questions on Stack Overflow referred to SQL Fiddle.
Surely this constitutes "a lot" of positive assistance to our network.
Does Stack Exchange support SQL Fiddle via cash donations and/or technical/infrastructure support?
If so, great.
If not, shouldn't it?
FYI the SQLFiddle "About" page has a link to stackoverflow very near the top, so SQLFiddle is also promoting StackExchange.
