Guys, I have a question:
Who's the king?
@wp, just like you I start feeling that the Suggestion subforum is useless.
Maybe it should be simply removed? Ooops, there is no one to do it

In my opinion the probable reason for this kind of "ignorance" is that the subforum "Suggestions" is intended for suggestions to the Lazarus IDE and the LCL and not for the forum and that therefore the administrator of the Lazarus forum doesn't read the postings here.

Without rereading the entire thread, IIRC it was expressed before that a need for such a subforum was not seen.

The "silence" may have the same reason: There are several moderators. None sees a reason to add the board, but each leaves the topic in case another moderator wants to pick it up.


About the poll:
The ratio does not really interest. People who do not need the board, will not vote at all. So it is expected that more than 90% of the votes will be positive.

If you want to take a ratio: count the amount of active users (active within last 30 days), and assume they voted "no". But even assume they voted 50/50, that would mean that the ratio was now 50.1% to 49.9% or similar.

The only figure of the poll that has any meaning is the total of yes votes.
13 people are interest. The rest of forum users (between 1000 and 9000) are not interested.


More boards also means more posts in the wrong board, and more work to move them to the correct board

Don't you think that the assumption of 1000 to 9000 active users in 30 days is a bit exaggerated?

actually since the first post was made on 19-06-2013 and we now have 03/2014 I would say that your 30days is a bit understated, it is 8 months already.

Yes, you are right, but Martin_fr discussed a time frame of 30 days.

@tazz: I know that the thread is older.

Don't you think that the assumption of 1000 to 9000 active users in 30 days is a bit exaggerated?

Why? Stats show, that just today 195 users were online. The most ever users online in a single day was 500 (feb 2013).

So in a month, I would expect it to be well over 1000, probably in the middle of the above range.

9000 is not what I expect. It is the theoretical upper limit. This should be obvious, assuming that anyone interested in figures would look at the forum stats. (actually it is Total Members:    9870)

As I said 9000 is not what I expect, since there are lots of no longer used (or leftovers of spammers etc).

1000 was simply a minimum, picked so low (based on the stats) that it was save to assume it would not be lower.

So the possible range is 1000 to 9000. Somewhere in there.

This conclusion is not justified, since most users will be returners. You cannot simply add-up the visitors of a single day to get total different users in a month.

If I added it up then I would have 200 (today) * 30 = 6000.
So clearly I did not.

There are no stats, how many users return every day. But it is save to say that not everybody does.
On threads ins which I participated I experienced reply times between less than a day, up to a week (in rare cases more).

The rest is guesswork. If you believe 90% are daily users, then my guess is to high. I do not believe it is 90% (not even close / surprised if it was 50%).

Also my input is not only the  200 of today. But feb 2013 (and there is no reason to believe, that we have lost significant amount of users), there where 560 in single day.

If you have 500 in a day, is it reasonable to assume that you may have over 1000 in a month?
Obviously it was a rare event that they all came on one day. But spread out over 30 days, I see no reason to expect a significant loss in numbers.

So I do stick with a minimum of 1000 in 30 days. (Personally, I would guess 3000)

Well, this thread, e.g., has 40 posts from only 12 different posters. That is a ratio of more than 3:1. Therefore, 28 posts originate from return visits, corresponding to a proportion of 70% returners.

Of course, this calculation may be not representative for the whole forum, but it is an estimate on an empirical basis, not a simple guess.

On the other hand, these calculations are not really important, because your second misconception is that you mix up members who abstain from voting with those who give a negative vote.

"returners" does not equal "every day returners"

If a user returns every 3 to 4 days (some may be once a week or less), then he is a "returner", but he does not come every day. So the 200 today, may all be returners, yet they are only a fraction of the user  that visit over the course of 30 days.

Anyway, there is no proof to any number. You re free to believe in a lower number. I do not.

Martin asked you to find out the online users for the last 30 days never said they were in the range of 1000 to 9000. He did said that the forum registered user count is in that range though.

No I meant that the amount of users that visited the forum in the last 30 days (meant to be a measure for active users) is in that range..

As explained 9000 (9000+ some) is the technical upper limit, but definitely not realistic.

It does not matter if a user posted or not. Just logged in.

This still does not answer how many votes ( %) are considered enough.
For exampe in the Free Pascal section there is a plenty of boards with 0 topics. Maybe "Windows", "Unix" and "Other OS" could be united in "OS Specific issues" .
Anyway, maybe 14 votes are and indication, that sharing my sources, etc. is a waste of time.

 

More boards also means more posts in the wrong board, and more work to move them to the correct board

On the other hands, topics get in the wrong boards, with no chance of getting in the proper place, since it does not exists.

I fully agree with Martin btw.  And I work in the field (Machine vision) even.
