I can see advantages and disadvantages to having a beginner, some of which would be:
- Allows beginners to find existing questions quickly and search in them
- Makes it easy for the casual internaut to ascertain whether a question would be considered beginner level or not
- Might make for a stigma if you tack it on a question. Personally I see no stigma in being new to a topic, but it depends entirely on how the community treats OPs with such questions
- It could also have similar disadvantages as the
homeworktag from StackOverflow
Admittedly it would be even better to be able to "vote" a question into "beginner", "intermediate" and "expert" categories, but lacking that a tag may just be the right compromise.
So I'm, putting this up for discussion.
Edit: So this is not about the particular tag - it was probably wrong to kinda limit the scope this way as it distracts people from the actual problem and seems to aggravate them - in fact it is about categorizing information. Seeing that Google Talks clip with Joel got me thinking. One of his main points is that search engines are bad at certain aspects, and while SE sites go a long way towards mitigating the flaws, there are still edges to be honed.
