You can't see who gave you karma,
I know you added that for completeness, but I actually very specifically -didn't- as k that question, because for me it doesn't matter much. I'm much more interested in which post (any)one found 'more than averagely useful.'
...and you can't see why
There was an interesting previous comment about that, that karma required a 'why.' Actually even though I've been 'doing net' for 30+ years I've seen forum software that gave -post- level karma type rating, I'd never seen -author- rating. I *like* giving positive feedback for exemplary or 'over the top' information and wouldn't -mind- the added burden of a 'why' comment. That's the sort of things that moderators would find useful as far as understanding users.
The 'war' thing, well, that's a social not technical issue, but can be dealt with technically. There *ARE* ways to analyse user actions to discover such activity, either deliberately incrementing or decrementing ratings for nefarious purposes. The admin reaction to that should be -not- to -delete- users (because they can always come back under another handle,) and not even to remove their karma abilities, but to set flags in the software such that 'somewhere down the line' (a few days later when the user isn't paying rapt attention) to remove the +/- karmas that they've carpet bombed. That would yield a more realistic longer term reflection of -average- user activity as regards giving karma +/-.
..."karmised", as you say.
I -researched- that word before I used it.
I can never think up anything original.
But oh well. https://twitter.com/karmize
I guess karma helps you build a good reputation on this forum, but as others have pointed out before it isn't that reliable if your karma can only grow bigger and not smaller.
Not necessarily. All it means is that the nefarious/bogus account (or even an active user) can skew the karma upwards and not downwards. But as I said if analysis can discover these accounts then their effects can be neutralised.
The Yahoo Answers 'game' is a great example of site admin -failure- to deal with these kinds of problems. I say game because there are ways to 'play' it that yield **TREMENDOUS**ratings with very little work. Eventually Yahoo simply changed this in a way that DESTROYED the ratings system rather than figure out how to deal with it. Personally I preferred to play it as a -real- user and -still- stay within the rules, and yet achieve high ratings. It was when they wrecked the ratings that I stopped playing.
You also can't see other members karma development or filter post on awarded karma.
Which would be fabulously useful, if it also has a keyword search system. Arduino.cc is a 'realatively' small site, 1.6M hits vs for example rcgroups.com which I'm very active in which returns about 10x more hits. The arduino.cc search too is pretty good because it uses google. Rcgroups uses a ridiculous that returns site search hits *and* hits returned via direct google searches as PAGES not POSTS. The site search, if you look for two keywords, and each keyword appears in -two- posts on -one- page of 15 posts, then you receive 'two hits.' Ridiculous. If you do a direct google search for those two keywords, you get only the one page returned, but because the two words might be in two separate posts and the two posts might have nothing to do with each other the 'information' returned is very likely useless. Again, ridiculous.
Craigslist is another example though, even worse, of *absurd* ridiculocity. They return -valid- web pages for 'flagged' ads. Meaning google doesn't filter them out -- it returns the deleted pages as valid hits looong after they're deleted. Google looks foolish but it's CL's -fault-.
Enough /RANT. Sorry, back to the point....
AND THIS IS THE POINT...
Arduino.cc isn't extremely large, but it isn't going to get smaller. There're an entire cottage and aftermarket industries built around Arduino. -Those- are only going to get bigger too. Admin has the choice of dealing with the problems NOW while they're perceivable -and- -identifiable-, or wait till it's too big of a bloated elephant to be -able- to deal with it. Or just ignore it and hope/assume the problem goes away.
Which it -ain't- gonna go away. In the digital future Arduino-the-product, the educational, learning and development hardware, -will- 'go as the site goes.' Meaning if the -site- isn't useful, viable, and evolving, then the -product- itself could -die- for lack of USEFUL AND EASILY ACCESSIBLE INFORMATION available to the user.
That's most relevant to the recent comment about 'wrong' information, which is worse than no information. http://forum.arduino.cc/index.php?topic=246152.0
If you want someone to know he did well, you'd tell him yourself you upped her/his karma by showing a + sign or just plain telling him they got some karma.
I do a variety, as appropriate in a particular situation and forum. If it's just 'thanks' I use PM, though only very rarely. More often I post it to the forum, but -also- add they 'why' or further information on the topic.
