Observe this lj_nifty post and its comments.
Apparently, the script advertised has a problem that causes it not to count anyone over 35, possibly because of problems related to using a representation of time that can't handle dates before 1970 (e.g. standard Unixoid time_t in some flavour or other). Count the number of top-level comments that comment on this, apparently without looking to see whether this point was addressed yet or not.
