I'd say otherwise. It's not like it's really important here, but in a book, that would be a very bright sign of amateurishness to me. Just like with sans serif dotless `i', `n' and `m' the only difference is not the number of the loops, the same with the hyphen, endash and emdash, they mean different things. Hyphen compounds words or breaks them across the line break, endash connects them in logical relations, and an emdash can stand for a colon or a pair of parantheses, indicating a subordinate clause that serves as an aside, generally. When these are mixed up, parsing the text becomes harder. It's not much of a trouble here in an internet title, but when this kinds of misuse appear in a long, difficult period in some rather complex text, it can end up consuming too much time.
