I don't think that replies updating a thread, and keeping people informed is an issue at all. But on other threads where discussions are being had, some people occasionally yourself, but plenty of others, appear to read a reply, reply to it, read the next reply, reply to it lol. Does that make sense.
Like I say, this isn't about picking people out, just about making threads easier to read. Of course I appreciate that sometimes, when you have limited time, it is the only way, quick ready, reply, work, and repeat.
No call for perfection or anything here, just my observations. I could be completely on my own here.
