Sorry, wasn't paying close attention, thought the issue was raised in connection with Silicon Valley businesses.
I'm not familiar with Florida law, but did a quick search and it looks like Florida is similar to many other states where non-competes have to (1) be designed to protect a legit business interest and (2) be reasonably tailored to protect that business interest.
Legit interests include things like trade secrets, confidential business information, relationships with specific customers, specialized training, etc.
Being reasonably tailored means it has to be appropriately limited in time and geographic scope. That will depend on the type of industry, the interest being protected, etc.
