Well, the title is quite self-explaining. I haven't read anything so far in Hartshorne's Algebraic Geometry, but looking at ME (and listening to what a close friend of mine told me about it) it really seems that one has to prepare to hard and painful days if interested in reading/studying it. Actually, ME has lots of questions regarding this exercise or that (not so clearly given) proof in that book, and so I wondered if it might be helpful to add a specific tag for problems related to Harthsorne's studying (just to order things a little bit more and improve searches).

What do you think about it?

• Sorry, I really meant to write about Hartshorne in my original post but I don't know why I wrote about Hatcher instead... Reason for downvoting? – Marco Vergura Jun 24 '13 at 11:44
• Voting works differently on meta. Votes on meta usually indicate agreement or disagreement. – davidlowryduda Jun 24 '13 at 11:48
• @mixedmath Ok, thanks! Still, I think it would be more useful and constructive (in general, not only for this specific question) if one pointed out his reasons for downvoting, so that discussions are possible... – Marco Vergura Jun 24 '13 at 11:51
• I think it's just too specific. If you mention Hartshorne in the question body it will turn up in the search anyway, so I see little reason to do that. – tomasz Jun 24 '13 at 12:05
• Understood. If needed, the question can be closed then, I'd say. – Marco Vergura Jun 24 '13 at 12:06
• This post seems related - it also suggested categorizing the posts based on the book, where they appear; but not using tagging system: Categorizing homework questions with textbook information in a way that makes the site act like a solutions manual – Martin Sleziak Jun 24 '13 at 12:20
• @MarcoVergura Just a heads up: Even though I disagree with your proposal, it is absolutely a valid thing to discuss. There's no need to close it. :) – Lord_Farin Jun 24 '13 at 12:40
