We have Stackoverflow for **specific** programming related questions. My [question](https://stackoverflow.com/questions/3707596/what-ui-technology-to-use-closed) was recently closed there for being subjective.

I have just found out that there is [a separate site for **subjective** programming](https://softwareengineering.stackexchange.com/) questions.

I remember having read on Joel's (or was it on someone else's, I just am unable to find the link), where the author was talking about how free tagging was introduced in Stackoverflow to overcome the associated tedious work of too many classifications and "sub forums".

But aren't we moving towards the same endless categorization through this? When there will be numerous Stack Exchange sites, then there will be need of aggregators and such, which were being fabulously avoided by Stackoverflow.

This is my first question on Meta and I found that it is asking for one of three compulsory tags and that is a nice way of enforcing multiple categories in **one** site.
