Sorry theymos, but this has just been revealed to be an utterly useless feature for our community.
Study the folks who are "dark" (and we can set aside the racist undertones of that particular glitch!) and you will find the most interesting people in the community, and certain the most opinionated. Is our goal to have a milquetoast all vanilla community of quiet, polite followers? Or is the purpose of a Bitcoin forum to celebrate bitcoin and explore the very edges of what a paradigm shifting financial innovation it is?
If I want boring and predictable there are literally tens of thousands of online communities that will give you nauseatingly boring. I participate here for the specific reason that there is healthy debate, outrageously polarizing opinion and people actually willing to stand up and believe in something, even when they are obviously disturbed and dead wrong, at least they have the huevos to believe in something.
The ignore button has become the mouthpiece of the intellectually retarded, and the cowardly refuge of those who are not able to form an opinion, preferring to hide behind the skirts of anonymous finger pointing and name calling.
A far more valuable button would be one that shows the interesting "darkies" exactly how many ignores each of the candy ass wimps who use ignore has implemented.
Do you have the moral courage to compile a list of who has the most ignores set to complement this uncalled for nonsense?
Hmmm... your view of this issue may a bit biased as you yourself have quite a few ignores.
The ignore button's purpose is to hide posts of people one does not want to see, given the freedom of expression the forum administration approves of, it is a useful option. I have tried no to use it myself until very recently (zyk and reeses) but I am happy I can now avoid reading their posts. I don't quite agree with your first statement regarding the 'dark' people, sure some of them may be interesting, but a lot of them are trolls who are ignored for a reason.
EDIT: Hue of the ignore button is simply an indicator of the probability that a certain person is a professional forum troll but one should use other measures to judge a person (read their posts and draw one's own conclusions).
