Yes, there is value. Finding information about it is non-trivial, it's on-topic, specific, and the two answers describe how and where to search for similar information. Granted, they both mention same source of information, and even though I could think of several other sources because I'm scheduling our chat room events and I've learned a thing or two about it by now, I concur the source they mention is good. Not everyone would know that, and there's the value. Zero down votes on any of the posts in the thread, zero close votes, no flags raised, no vague answers and fairly good number of views attests to that.
I can assure you that finding reliable information about future spaceflight activities isn't a trivial matter. Many new players add to the confusion with no clear and established place where you'd usually be finding information. For example, since I mentioned I could list some more sources, here are some more:
As you can see, it's a mess and launch and launch related event dates are often tentative, launches are scrubbed for all kinds of reasons and reliability of information matters. It's not a set and forget business. Presented information needs to constantly update as new information becomes available. If you get two answers and a comment all endorsing a single source, then that means something. That, on its own, is valuable information.
For what is worth, I'm often in two minds about asking similar questions as I get to scheduling events that aren't as clearly set in stone as some others might be. For example, I'd really like some more information on the inaugural Super Strypi (SPARK) launch from Kauai, Hawaii. But as this is an entirely new program (LEONIDAS - Low Earth Orbiting Nanosatellite Integrated Defense Autonomous System) not much is known about it. Yes, if I'd ask when it will launch and where I can get more information about it, it wouldn't age all that well once it launches. But if I got helpful answers, it would still be valuable information to me that asked the question, and hopefully to someone else too.
