Hmmm... well, I want to thank everyone for that wonderful round of indifference.
Chris, you really should pick up on this - and judging by the flood of responses I'm getting, I'd say there's a lot of pretty ticked off DOS 4.0 Shell programmers out there too...

Your welcome Tim 
Seriously though, I didn't see your post because I was gone almost all of yesterday.
I honestly didn't know it was possible for someone to spend 2 hours looking at artificial flowers.  From now on, the next time my mom asks me if I want to go with her and my grandma shopping I'm gonna run far far away.

Hey Tim,
You're absolutely right - but at the moment it's sunny, it's Sunday, and I'm listening to some very smooth trance while making blueberry muffins.
Ping me on Monday 
cheers,

Hmmm... are you saying that 'Small shiny objects' might not be right up there on the must have list? Fair enough, seeing as how you refrained from adding 'Smooth trance'.

As long as you're working on CP.Net...
What if the article ratings showed the standard or average deviation along with the average? These values are pretty easy to calculate and can give you a good idea as to the accuracy of the beloved 'average' value.
If you're worried about scaring people away with terms like "standard deviation", you could calculate the StdDev then scale to a 1-10 range and call it something like "confidence" and represent it with a little graph or something.
Here's a little example:
Article A: 3,4,4,5,4,4,3,3,3,3,3,2,2,5,4,3,3
Article B: 5,5,5,5,5,5,5,5,4,4,4,1,1,1,1,1,1
Take these two sets of hypothetical ratings, for example. They have the same average (3.41), but B should probably be considered a more highly-thought-of article. Those 1's in B look out of line with the the rest of the values - it should be rated much higher. The ratings for article A, though, make sense - it's mostly 3's and 4's.
A avg: 3.41
B avg: 3.41
Through the magic of Excel, we get the Average and Standard Deviations:
A AvgDev: 0.719
B AvgDev: 1.418
A StdDev: 0.870
B StdDev: 1.660
Each of these values is much higher for Article B. This confirms that the ratings for A are more consistent than those for B. You could interpret this to mean that A's average more accurately reflects the majority of its ratings than B's average does for B's ratings.
This is all basic statistics, nothing crazy.
And here's the "confidence" thing i was talking about. I'll just scale the StdDev to a 0.0 to 1.0 range.
A Confidence: 0.692
B Confidence: 0.412
Or, A's confidence is at 70% while B's is at 41%.
Conf = (2.83-StdDev)/2.83. 2.83 is the maximum StdDev for data in the range 1 to 5 (i think ).
(this "confidence" is just something i made up, it's not related to any real statistical calculation)
it's friday, i'm bored

You could also confuse the hell out of everyone with the equation for calculating the standard deviation:
SD = √Σ(x - avg.(x))²/n

There are such things as confidence intervals that allow you to represent your data. We can say that a random variable will fall within these two ranges of my dataset(SomeNumber, SomeOtherNumber) with XX% confidence.
These are calculations that have existed for a long time.

yeah, i knew "confidence" was a reserved work, so to speak, in statistics. i just didn't remember what it was for .

No Problem, I forgot to mention in the last post that it was a really good idea. Thanks Chris

This won't help if we get some idiot voting 10 1's. It's also going to add a lot of storage/processing time.
But - definitely something to think about.

Instead of showing the average just show the total. Thus even a 1 is useful. If someone gives me a 1 my total still goes up. Don't show the number of votes or the average. The advantage with this is that now nobody can artificially bring an article down.
A nice total-count system is a lot better than an abused-average system.
And perhaps one more rule. Only members with at least 150 posts and 2 months of membership are allowed to vote. This helps to avoid the [sign up, vote, sign up again...] situations.

Good idea! At first i thought that sounded awful, since poor articles with lots of people voting would still get higher ratings than some good niche articles... But for a given category, the rating would still give a good impression of which ones were more favored - while at the same time reducing the rational for malicious down-rating of articles, since cross-category comparison would be useless anyway.

150 posts sounds like a huge number. Ok, maybe not for you  . But still, isn't that maybe overkill?

The point to be noted here is that poor articles wont get votes. Each vote counts. A 5 counts more than a 1, but a 1 still counts. Thus instead of 5 being excellent and 1 being poor we have 1 being good, 2 better, 3 still better 4 very good and 5 excellent. And a 0 [no-vote] means bad. If the total for an article is 0, it means that nobody found it useful.

How can we control spam on here, just started to notice it, there have been several posting with the title "Excellent Free Technical eBooks", of course from an Anonymous user?

DirectX is completely unnecessary - check out my articles in the GDI+ section, this GDI+ code is easily ported to C++.

Chris,
Since we know that you are laboring so hard to get CP converted over to ASP.NET, I do have a question. Do you think that with the new version you will be able to automate the method to update articles? I am referring to the articles that have been moved outside the useritems section/folder.
