Here's the main problem with stepquotes: EVery letter in a stepquote, especially the 90-degree angle bends, are essentially unchecked. So every single crossing word needs to be unambiguously clued, and easy enough to understand. A few obscurities, or ambiguous answers, forces holes in the quote that can only be resolved by solving other letters in the quote. Too many blanks, and the puzzle becomes essentially unsolvable.
In the Maleska-edited stepquote puzzles, you often essentially needed a crossword dictionary to resolve the multiple African towns and obscure animal names that crossed nothing, in order to decipher the quote. So construction, cluing and the solving experience can be unpleasant, unless great care is taken in design.
