Activity & new membergroup limits

Well, I registered back in march. Going to take awhile to rank up. Doing it all over again, YES!

Checking out the new features. Nice idea.

time = number of two-week periods in which you've posted since your registration
activity = min(time * 14, posts)

I don't like it.

It embodies the assumption that any post above once per day (averaged over two weeks) is not contributing; which I do not agree with.

At the very least number of posts per day should be increased, e.g. min(time * 28, posts).

And you should consider more sophisticated metrics such as sum of f(x) over all two-week periods, f(x) being x / (1 + sqrt(x/14)) or x / (1 + x/28).

Time spent logged in will also be useful to include as a component.

Now let's take the indefinite integral of that function...

Challenge accepted!

Code:

                                         3/2
                             2 Sqrt[14] x
28 Sqrt[14] Sqrt[x] - 14 x + --------------- - 
                                    3
 
  392 Log[14 + Sqrt[14] Sqrt[x]]

Or

28(x-28log(x+28))

I had to use an integrator of the first, the second was easy to do by hand.

So, I'm already a hero (just not yet). hehehe.. Just need to post once every 2 weeks. But I already post every other day.

A complex solution that is well thought out. I have an issue with this though (besides being too complex) it does not address the fact that it will reward trolling kids with plenty of free time instead of more mature contributors who actually add value in their discussions and posts.

I would like to see what you have implemented theymos incorporated with a points system which the community can upvote or downvote individual posts based on content. Similar to Reddit and Hacker News.

The idea is to discourage posts with no relevance to the wider community and reduce the number of flamewars and trolling.

Think of it as community driven forum moderation.

but mob upvote/downvote kills diversity, and new ideas, entrenches to much of the normative. We wan't the tails of the bell graph, gotta take the good with the bad

[theymos]

There won't be a global scoring system. Such systems are sometimes useful/entertaining, but they're bad for serious discussion. Go to /r/Bitcoin (which I also moderate) if you want that.

Maybe at some point there will be a WoT post scoring system, but as I look at the deficiencies in this semi-WoT Trust system, I'm less inclined to build anything else off of this. A more sophisticated WoT system is probably needed for that.

how come I got whacked from being a Hero? I've been here for 2 yrs I think (6/5/2011)
I guess I don't get this system

You must have had long stretches of inactivity.

is it using any active two week period towards activity or is it active two week periods since last inactivity?

[CanaryInTheMine]

feature request: on my profile, i'd like to see a graphical (simple will be just fine) time line and the periods of activity/inactivity that contribute to such.

[theymos]

It's over all time.

[cedivad]

I think that it should be more of something like this:

time = number of 1-day periods in which you've posted since your registration
activity = min(time, posts)

That'd make people feel paranoid about always getting a post in each day, I think.

You are right about this. However, on the other side, I think that 2 weeks is a too long timeframe.
I guess that the optimal should be 1 week, or 5 days.

Anyway, 2 weeks is not that bad, since that the basic idea is good.

[Operatr]

Makes sense, I was able to go from no one to Hero in the span of 3 months...seemed kind of unfair to those who have actually been here since day 1 that have made the greatest contributions

its already there.

click profile then click show stats in the left hand corner

for example here is mine:

Thats posts by time of day. I think CanaryInTheMine was referring to posts over each monthly or maybe weekly period.

[barwizi]

Why not have a coloured coin system forum wide? frequent posters get certain colours, maybe all blue turning to green then purple then gold then platinum for the highest rankers. You can have platinun coins but be a noob, that just tells us that he's a spammer and/or troll.

correct.  a visual representation of "activity" as it is seen by the formula now used.

[Dougie]

Interesting idea! I like it. Was a bit confused that my post count had been cut this morning!

[b!z]

In the PM system, posts have not been replaced with activity yet. Is this intended?
