I guess it depends. I maintain that getting something mostly working is not that hard. But I haven't worked on a webapp that didn't have many obvious (to me) concurrency bugs in them.

So does that make it easy or hard? I dunno. Maybe writing correct webapps is hard, but maybe their correctness doesn't really matter.
