According to [1], disambiguation was one of the meanings for the Ø symbol. --Love Krittaya (talk) 00:10, 21 August 2013 (UTC)

Somewhere use Ø symbol for average speed. [2] --Love Krittaya (talk) 00:10, 21 August 2013 (UTC)

Speed is irrelevant here. What goes on is that the diameter symbol ⌀ is also used for (any kind of) average. This is common in central Europe (see e.g. [3]), but not so much in English-language sources.—Emil J. 10:44, 21 August 2013 (UTC)

## MOSDAB

Two biggies here (hence marked for cleanup):

1. The WP:PRIMARYTOPIC style
2. Prize for the most (Over)use of templates on a dab (i.e. nested, and lots of them!), which per WP:MOSDAB are discouraged
1. Links at start of entry preferred - although nice to see them line up with angle brackets - is this deviation from MOSDAB justified?

Was half way through cleanup, then saw I'd cleaned this before [4], so ping editors since then with proposed version: User:Paine Ellsworth User:Kendall-K1 User:Sj User:Codehydro User:TomS User:TDotO User:Daf User:EvenT User:Kwamikagami.

edit summary was "cleanup according to WP:MOSDAB - primary per MOS:DABPRIMARY (overview WP:DABYESNO) - note templates are discouraged per WP:MOSDAB and seem highly irregular/unjustified?" 19:03, 17 November 2015 (UTC)
Agreed on PRIMARYTOPIC and putting the link at the front. I'm not sure about the odd-looking quotes (angle brackets?). Often single letters will be quoted so the reader knows we're discussing the letter, not using it in a sentence; but how many people are familiar with this quoting style? Kendall-K1 (talk) 19:33, 17 November 2015 (UTC)
Yes, never seen it before on a dab. As so many editors kept this version, I thought I was missing something. I implemented the latter before (link above for how it looks), so desirable to get consensus so it sticks? 20:16, 17 November 2015 (UTC)
Bracket#Angle brackets In linguistics, chevrons indicate graphemes (i.e., written letters) or orthography, as in "The English word /kæt/ is spelled ⟨cat⟩." TomS TDotO (talk) 01:54, 18 November 2015 (UTC)
This isn't about the correct use of angle brackets per se in an article, that's no doubt more clear to you than me, but dabs are only navigational aids and I suppose can be thought of as boiled down. Yes we follow style, but within reason - we have nested templates here! How can we try to avoid templates/complexity? So the question is can we get away without using them? What do other dabs do? We have a similar issue with math characters. 10:30, 18 November 2015 (UTC)
As far as I'm concerned, use of the angle brackets here is pedantic (they are important in technical discussions to make distinctions) and it would be helpful to the general reader if they were totally eliminated. If that's what you're talking about, I agree. TomS TDotO (talk) 11:56, 18 November 2015 (UTC)
Yes, said better than I did. 12:12, 18 November 2015 (UTC)

Where Why are there three links to disambiguation pages in the See Also section? Two of them aren't even real, they are redirects to non-disambiguation pages. Kendall-K1 (talk) 13:12, 18 November 2015 (UTC)

See latest change. If this doesn't address your concern, let us know. TomS TDotO (talk) 13:39, 18 November 2015 (UTC)
I undid the removal of Null sign (disambiguation) - it is a valid link to a dab page (and was in originally). I propose adding Disambiguation (disambiguation) as I believe the character means disambiguation, so worthy of inclusion in the See also. 13:50, 18 November 2015 (UTC)

Having now read WP:INTDABLINK and WP:FURTHERDAB it all makes sense to me now. I had not encountered this use of dab links before and it still seems odd to me, but is apparently correct. Kendall-K1 (talk) 14:07, 18 November 2015 (UTC)

It doesn't make sense to me. (1) "Null sign (disambiguation)" redirects to "Null sign" (without "disambiguation"). (2) I wasn't aware of the null sign meaning "disambiguation", but putting it under "See also" does not tell me that it does. Why not put it in its proper place? TomS TDotO (talk) 14:58, 18 November 2015 (UTC)
(1) is covered in WP:HOWTODAB. Kendall-K1 (talk) 17:38, 18 November 2015 (UTC)
Changed to Null symbol (disambiguation). User:TomS TDotO There's discussion of it meaning disambiguation here-> Talk:Ø (Disambiguation) (see EXT link interview), but because it's not very authoritative and a quick look in wiktionary and WP didn't find anything, I thought See also was appropriate (there's many similar looking symbols so it may be in fact be in one of those). If nobody objects I'll put back in? 18:51, 18 November 2015 (UTC)
I guess I don't have a strong objection, but it seems confusing because there is nothing on either this page or at the target page about this meaning. Kendall-K1 (talk) 19:37, 18 November 2015 (UTC)
As to (1), it was just my mistake. As to (2), I agree with User:Kendall-K1. TomS TDotO (talk) 02:22, 19 November 2015 (UTC)
2. agree is a bit tangential (it explains why we have an album title similar to a dab page title). User:TomS TDotO I only now saw that I'm having to clean this a second time because of your edit [5]. Pls can you familiarise yourself with WP:MOSDAB before editing dabs. 06:58, 19 November 2015 (UTC)
