Sure, after browsing through topics for a while most people can guess that Slither, Johnny, and Cerberus are staff, and their words more often than not hold finality on Sindome related topics. But it just makes it easier for new players to have access to this information from the get-go. For example: between players, there is discussion and back and forth about different ideas, and while there is lots of friendly discussion between staff and players as well, a staff member saying that an idea is "not going to happen," is very different from a player saying something is "not going to happen."
When an answer like this comes from a staff member, this can be a signal to either drop the subject entirely, or shift approach to what is being discussed. And I think it should be easier for new players to realize this.
And eventually when a player does get around to the point of searching through older board topics, there's sometimes speculation involved with determining the possibility of a post being form an older, possibly inactive staff member. I have no idea if Linekin is around any more, but regardless of that I'm sure their word on previous topics holds just as much weight now as it did back in 2015. Possibly not, since they haven't posted since 2015, but anyway the guess-work should be taken out of determining who's a staff member on the boards.
