I'll just wait until other users have figured out which ones are useful and which are a waste of time, let Google kill the ones that fail and iterate on the ones that don't until either everyone else adopts the same strategy as me or Google figures out what the heck they're doing. I'll set an alarm to remind myself to check back in 5 years.

I've been early adopting Google products for years, many of which sadly nolonger exist. That's the problem.
