This (more stupid bullshit) was my initial reaction but it's ultimately a very subjective thing. Tim O'Reilly's piece the other day reminded me of that. Only the people who make something can tell you whether it was worthwhile for them to make it. We may not like it and we may think it's a waste of time. But the creators might not.
On the other hand, it's sometimes hard to be honest with yourself about this. There is the pet rock mentality which says "if I can just build something stupid that everybody falls for, then I can make a lot of money and it will be so easy." Looking at Web Kare, I actually don't think this was their approach at all, but I hear different versions of this all the time. If you ever catch yourself saying something similar, then it's probably worth examining whether you really think it would be a worthwhile thing to build.
