That's why the way most people write web crapplets lands my clients in court, why web crapplets tend to be a giant middle finger to usability and accessibility, and why for MOST businesses who's business isn't SELLING crapplets the use of crapplets does more harm than good!
Did I mention the legal issues?
But again, I'm an accessibility and efficiency consultant. I get hired to teach companies how to fix their problems when idiotic scripttardery and ignorance of accessibility norms lands them in trouble
Thus why I'm not exactly "app friendly". There are plenty of cases where they make sense, but most businesses and websites should in fact avoid them if they're not live-service driven!.
