Maybe the "you" market isn't that large? Everybody tends to assume that their needs form a large market. In any case, presumably you did not find something like Weebly a hard problem -- most programmers don't -- yet we're undeniably providing value to quite a few people: 1.5 million and counting.

You can't criticize someone for working on the needs of a large market, just because that large market doesn't happen to include you.
