In-line Query --- Advices pls

I'd like some advices on the use of in-line queries....Select ....from (select...from...)
Is this something that freaks out the "typical" DBAs ? what about joining it with other table(s) ? What sort of care should be applied ?
How common is it used in your experience ?

Thanks
