So, I think I've sort of explained why things disappear that I like. I'm the kind of person who [endorses a deep commitment, getting healthy getting good pay is what I live for--sorry...involuntary Savage Garden quoting is a sickness that affects millions every day. Repost this if you agree.] doesn't jump on a trend right away. I'm incredibly wary of new things, and I wait a long time before I hop on any kind of trend or new product or fad. And, thus, by the time I get in on something, it's likely to be on its way out.
That could explain a few occurrences of this phenomenon.
