Do you mean selling uncovered calls? With a covered call your potential profit is capped, but you aren't exposed to the infinite risk of buying the stock (since you already own it) at a bananas price if it exceeds your strike.

Selling covered calls can be a fine substitute for limit sells if used carefully. Assuming one is comfortable selling at the strike price, the covered call trickles a little profit in the meantime.
