Column name naming conventions and best practices

I would like some expert opinion on best practices when it comes to **column naming**. The background is that [according to Wikipedia](http://en.wikipedia.org/wiki/Join_(SQL)#Equi-join) , the following syntax, SELECT ... FROM Employees JOIN Timesheets USING (EmployeeID); is more efficient than SELECT ... FROM Employees JOIN Timesheets ON (Employees.EmployeeID = Timesheets.EmployeeID); However, the JOIN ... USING syntax only works of *all primary key columns have globally unique names*. Thus I wonder if this is considered The Right Thing to do. Personally, I always used to create tables with PK column id, and foreign key column othertable_id. But that way it's not possible to use USING or NATURAL JOIN. Any links to design styles or best practice guides for table design would be appreciated, too!
