- Thank you. I see you caught my misspelling at Tolperisone, too.
[edit] Removing Categories
Why are you removing all the categories from these chemical compound articles? Silverchemist (talk) 19:18, 29 May 2008 (UTC)
- I'm not removing all the categories. I'm only removing the redundant ones. For example, if isopropanol is in Category:Alcohol solvents, which is a daughter category of Category:Alcohols and Category:Solvents, then Category:Alcohols and Category:Solvents are redundant and should be removed per WP:SUBCAT. ChemNerd (talk) 20:08, 29 May 2008 (UTC)
- Then why not remove the daughter category? It seems more useful to have the ethers, or alcohols grouped together. Not all alcohols or ethers are used as solvents. Silverchemist (talk) 20:30, 29 May 2008 (UTC)
- I'm not sure I understand you. The categories for ethers and alcohols are daughter categories, too. So why not remove them? Not all organic compounds are ethers or alcohols. ChemNerd (talk) 00:13, 30 May 2008 (UTC)
- WP:SUBCAT#User benefit rule "Does the removal of duplication affect the reader, making it hard to browse through subjects or spot their target easily? If the answer is yes, you should not remove the duplication." If a reader is looking for a listing of ketones, it is not obvious that they should also look at the daughter category of ketone solvents. Classification by "ketones" is based on composition while classification by "solvent" is based on use. Silverchemist (talk) 04:14, 30 May 2008 (UTC)
- I guess we just see it differently. To me I think it is obvious that someone looking for ketones will look under ketone solvents too, just as someone looking for a list of organic compounds will look under ketones too. In any case, it's not a big deal to me, so if you want to add the additional categories back, I'm not going to complain. ChemNerd (talk) 10:55, 30 May 2008 (UTC)

- ChemNerd: Please reconsider your recent recategorization. It puts undue weight on one of many (probably even more important) aspects and uses of a chemical compounds. At least reinstate the original general category. Also, in my opinion it does not make much sense to subcategorize solvents by chemical functionalities (amines, ethers,...); other schemes would make equal or even more sense, such as bp, logP, H-bond properties,... Please also notice that the categorization system does not have to be strictly hierarchical top-down. Thanks, Cacycle (talk) 13:52, 30 May 2008 (UTC)
- I'm not the one who created those categories - I just saw, for example, that some alcohol solvents were categorised in Category:Alcohol solvents and some were in Category:alcohols and Category:Solvents, so I consolidated them in the subcategory plus I also removed redundancies. It seemed perfectly logical to me, but I suppose I'm in the minority here. I won't make those kinds of recategorizations any more. If those subcategories shouldn't be used for the handful of chemical compounds that I moved to them, then I suggest that those categories shouldn't exist at all.
