I guess it doesn't matter much, now. But in 1977-1980, "Starlog" magazine was just about the only reliable source of information for a lot of us, cutting through the rumors about what was going on with the Star Trek revival - first the Kaufman movie, then the "Phase II" series, then ST:TMP, then the removal of Roddenberry and his replacement by (horrors!) that guy who did "The Six Million Dollar Man" - somebody named Bennett...
Seriously, over time I figured out exactly what day of the month the local "Drug Fair" would shelve the next issue, and calculated from other available information just how far in advance of publication the 'zine's editorial deadline was - anything you read in "Starlog" was six weeks old, and that was pretty damned fresh and up-to-date. The first pictures of the new Enterprise sets, the new exterior design of the ship, the first rumbles of trouble with the effects on the film and possible release-date issues...found all that out in "Starlog."
In 1981 I discovered "Variety" and then it didn't matter so much. But damn...everything changes and nothing lasts forever.
