A 'this has been read by a blue' tag may not be as useful or have as much of an impact as you'd think. Reading a large number of threads about class balance doesn't directly imply that a post about that topic was imminent. Criticism would turn to our reading habits; the threads we've been reading or not reading.
This really depends on the particular forum being read. For instance, this would probably not work on the general forums however the bug report forums should be done this way. Take for example bugs relating to Blade lord that are particularly destructive in heroic mode that I first reported in October. There has been no mention publicly or a fix so from my point of view I can only assume that people have not seen the thread or the information has not been passed along to the devs.
This is not such a big thing with feedback, but I am not talking about feedback I am talking about something in game not working as intended and something that still persists to this day which means no fixes for several months on a PvE end game boss which seems a little stupid.
In the end I gave up on the forums and reported it in game instead and got to spead to someone who confirmed there are some known issues with these mechanics and they are "looking into it" yet from my perspective on the bug report forums no one gave a !@#$. This is the kind of non response that then breeds the animosity to the general chit chat posts from you guys.
There are forums that should not receive blue notifications for everything, or need a notification about everything, but the bug report forum should be working more similarly to the tech support forum and there should be active presence on that forum. In addition, when things are reported and confirmed that it is an issue, there should be a "Read me first" with all the current issues - and do not point me to the current one because it is not updated properly.
The point is, communication requirements do vary from place to place and I am not going to have a go at you for posting chit chat posts in general about things not important but do not expect everyone to be happy when posts that should be getting responses by default are not being done properly.
