I think FD have a bit of a dilemma - if they give us an actual lead the horde descends on the mystery and it may get found and blown up in a few hours, and if they give us nothing then, well, nothing happens. The former probably results in huge investments of their time in creating things being burned through very quickly, while the latter leads to player frustration and boredom. I don't know how you get around this.
All I can think of is to break mysteries into many small parts, so that many people can participate (find or solve something), but nobody can crack the whole thing open by themselves. At least, not until many people have shared what they know.
I literally sat up waiting for the galnet article, went to sleep frustrated it hadn't turned up (different time zone), and then EAFOTS/gap/confluence probes had largely been found before I got out of bed![]()
I'm in the same boat (GMT+5), so everything is announced and then solved while I'm still at work. That's actually why I like the Rift mystery - it doesn't all happen when FDev decides it's going to happen (or in the case of the alien crashsite, BEFORE). The clues aren't treasure hunt style - it's an intellectual exercise, not how quickly you can pass something through a devrypter in the internet.
