I agree, and I'll go a step further, risking HN pariah status in doing so:
Comic Sans is a Good Thing.
That capitalization isn't accidental. It, and every other easy to [mis]use cute, fun, and simple thing we've seen in the last couple decades have been incredibly beneficial to the tech industry and humanity as a whole.
When the Mac and Windows came around, a lot of "computer people" hated them. They were slow and inefficient, and hurt productivity. RMS still rarely uses a mouse. That's fine for people like us, but it isn't fine for people who use a computer to keep in touch with friends or make lost cat posters. And the simple fact is that there aren't that many people like us. Casual users are by far the largest demographic, and that expanded market has been a huge boon for us.
The proliferation of "toy" apps is no different. By sending the message that "you too can make an app", we expand the market hugely. That helps everyone. So what if most apps are garbage? Most websites were garbage in the 90s, but without them we would never have had the Internet that we have today. We needed that huge variety of sites for people to think the marketplace was worthwhile. Now, the Internet is mature, and we almost accept as an inevitability that it should be that way. It wasn't. Without geocities, porn, and even AOL it would just be a graphical Usenet with 2% of its current users.
We're in a Geocities phase right now. There's a proliferation of garbage filling up the mobile sphere. Without that garbage, however, the sphere would be much smaller. Eventually, professional companies will step in and improve overall quality, but we need size at the moment. It grows the market, and it's good for everyone.
