Back of envelope: suppose one 200-byte comment/post per minute every day for 5 years (I guess 200b is below mean length, 1/minute is above mean frequency, and I think LW is older than 5 years but younger than 10). That’s 5 x 365 x 24 x 60 x 200 bytes. Round everything off to powers of 2 and 5: 5 x 400 x 25 x 50 x 200 = 500MB. So, less than a gigabyte, never mind a terabyte.
