Q:

We are out of new [design]s

This tag has been burninated. Please do not recreate it. If you need advice on which tag to use, see the answer below. If you see this tag reappearing, it may need to be blacklisted.

design has 17,597 questions as of this writing, 1,360 of which are closed.
According to my favourite search engine, the definition of design is:

To conceive or fashion in the mind; invent.

Following Shog9's procedure from MSE:

Does it describe the contents of the questions to which it is applied? and is it unambiguous?
It does not describe the content of the question whatsoever, because it is incredibly ambiguous.
The term "design" can be applied to literally any decision made in any circumstance. It can be about OOP inheritance trees design, UI, database tables, system architecture, ...

Is the concept described even on-topic for the site?
Well, this is so ambiguous that at least part of that tag has to be.

Does the tag add any meaningful information to the post?
This tag means "Some decision has to be taken / thought of". This can be said of every single question that is asked on Stack Overflow. No meaningful information whatsoever is added by this tag.

Does it mean the same thing in all common contexts?
No. There are too many meanings in too many contexts to pinpoint one specifically.

I do not think there is any way to replace that tag with any other.
[design] adds no information to questions and really should disappear.
A close friend of that tag is design-patterns (21,233 questions) with 2,252 common questions. Re-tagging some questions with that tag should be discussed.
Please do not discuss design-patterns here and instead focus on design itself. If you wish to discuss design-patterns, please ask a new Meta question.

Please note that burninations are not just tag removals - They are the process of carefully moderating a specific place of Stack Overflow. Avoid mass-editing the tag out of questions as it is counter-productive. For more information, see Shog9's answer on MSE or the official burnination process.

A:

Per the tag's own wiki (emphasis mine), the tag is purely opinion-based:

Design in programming is the act of making particular choices about how best to structure a program, to achieve goals of reliability, maintainability, correctness or ease of use. 

We should burninate it. 
Questions could conceivably exist with only this tag, but such questions would, by the very description of the tag, be opinion-based. In other words, close-worthy. Other, more specific tags such as design-patterns and responsive-design exist already, so we won't even be losing much useful tagging context. 
PS - We should probably lump design-rationale (15 questions) in with this.

Observations/Retag Guidance:
Given the gigantic size of this tag, the burn will be initially time boxed to one week. If, after a week, progress is still steady and the community is still interested in continuing work on the tag, the deadline will be extended. Following that, the CMs will remove the tag from the system.
For that reason, it may be worthwhile to target the questions which were not very well received first.

Progress:
The design tag is in the process of being burninated. You can help out by reviewing the questions with this tag, and...

editing questions (to improve the question and remove the tag),
flagging/closing questions that are duplicates/off-topic/unclear/too broad/opinion-based,
filtering on this tag in the Close Vote Queue,
voting on questions with this tag,
voting to delete the questions with this tag (after they have been closed, and only if the entire Q&A contains nothing of value). However, keep in mind that at the end of the burnination process all closed questions containing this tag will be deleted automatically. Thus, there's rarely a need to vote to delete these questions.

Thanks to g00glen00b and Jon Clements for setting up Gemmy to guide us in burning this large tag.
Remember that burnination is a clean-up effort!
Salvage whatever possible by editing and re-tagging.
We don't want to destroy value, so salvaging a post should be your first priority. If a question can be saved, please edit it. Your edit should improve all problems with the question and remove the design tag, possibly replacing it with another tag, as described above in "Observations/Retag Guidance". Editing is best left to users with full-edit privileges.
Unsalvageable questions should just be flagged/closed. They don't need to be retagged.
If the question is not appropriate for this site, then don't worry about removing the design tag—just flag/close the question it is attached to.
At the end of the burnination process, all questions that still remain with the design tag should have been closed. These will be mass-deleted, which will remove the tag from the system automatically, with minimal disruption.
Ask for help if you need it.
If you have any questions about specific questions you come across, or the process in general, please feel free to leave a comment on this post. You can also drop into the SOCVR chat room for real-time advice and discussion.

A:

This tag should definitely be burninated. The third result in the design search already had nothing to do with "design" (at least as of my search). Additionally, the tag is so broad that any question that could somehow fit itself to the tag would likely be closed as "too broad" as well.
