For some reason I tend to agree with SerqFeht, on the other hand though I actually cant really imagine RPers going to constant mining all of a sudden. Just doesnt make that much sense to me. To safe trias while its that easy to gather may be sort of valid, but I would expect RPers to mine for a shorter time - but meanwhile we have that situation for several weeks now, and I never read about any RPer explaining to be "unavailable" because he's mining for 6weeks now (feel free to link me to an opposite). And having extremely crowded 100m², with mostly mute or "wts"'-ing miners should hardly be a reason for RPers now move over to Gugrontid - would it?
After all though I see it as the only major "new feature" since 0.4 (besides /introduction) - probably thats why I tend to agree here nonetheless.
To not see nametags floating above heads I dont take as discouraging to go for casual events (to avoid the term "RP") with bypassers. It surely took some time to get used to that apparent anonymousity, but its in fact no difference if you see an unknown name or no name at all. The main problem is there just are hardly random bypassers.
I would like to once more mention though, that the forced anonymousity is way too unrealistic, and considering PS a game (-> fun!) rather tiring, since you wouldnt recognize someone who you might know as the one usually sitting at the pub from 20-22, or often carrying planks (or whatever). I feel, hard to say, "isolated", or some sort of limited in my senses nowadays, and that effect of being "limited" may cause one being focused more on people I already know... guh, no idea.
Again: Extend that system (dont revert), make it for people can add custom nametags, and perhaps players will even be intruiged by simply finding out features of chars to enrich their individual appearance of PS by fancy nametags.
To what Leama says: Same experience here, my BL is red much more often than it once was. The reason for that I see in what I said earlier, that within the first weeks of 0.4, having to face the same char over and over and over again without a nametag may have annoyed or tired people for they may have left.
