Have you had the experience of someone responding to something in the same way you were intending to if you had acted first?

I’m referring to things like finishing another person’s sentence, but also to something that happens particularly often in internet discussion threads, and particularly on Reddit. Someone will ask the exact same question or give the exact same comment I had in mind, usually phrased slightly differently, but it’s close enough and it happens often enough that it’s quite remarkable. Reddit half-jokingly calls itself “the hive mind” and fluther is “the collective”. Perhaps there’s a deep significance to those terms, especially in the context of the internet, that we’re only beginning to understand.
