Post History

If you'll allow me to come up with a made-up dystopia community scenario: 

Suppose you are a professional carpenter who like to discuss your trade with other professionals. So you start a carpentry site.

The first thing that went wrong was that the site attracted a lot of "do it yourself" amateurs, asking horribly basic questions along the lines of which side of the hammer to hit a nail with. While these questions are technically still about carpentry and tools used by carpenters, they are very uninteresting for the professional and distracts from the questions that professionals find interesting.

Then someone decides to merge the carpentry site into a major "Houses" site. Now you aren't only distracted by on-topic but basic carpentry questions, but by completely different topics as well. Home decoration, architecture, house brokers, plumbing, household electronics, gardening... 

Many of these other topics do interest you, since they are somewhat related to your trade. But you aren't really qualified to answer any more in-depth questions in those topics. So you and everyone else settles for answering the easy questions only. At the same time as you write answers to easy gardening questions and having a good time doing so, you notice that the amount of interesting questions below the carpentry tag have for some reasons decreased. Instead the amount of shallow, easy to answer beginner-level questions has increased. That's strange... now where was I... "yes, you must water the flowers on hot days or they die".

Then someone decides to merge "Houses" into the the "Cities" site, which is about everything that happens in a city. Now you an even broader range of topics: traffic, city planning, night-life, tourism, people asking for directions. The site is now so broad that it's impossible to find any interesting topic at all for anyone. 

All the carpentry experts has fled since long since they hold no interest in 99% of the site contents. The only type of questions remaining in the carpentry tag is them DIY dudes struggling with their hammers, the site get thousand such questions every day and tons of questions, but barely any answers. The quality of the few answers is very poor, because of the lack of domain experts willing to answer or review other answers. You can however post an answer about how to use a hammer on screws and get tons of up-votes in no time.

It is dead easy to post a question on "Cities", almost everything is on-topic. But it is almost impossible to find a question to answer. And then your carpentry questions about screwing got you suspended because the night-life admin with zero domain knowledge of carpentry found them obscene.

Then someone decided to merge the "Cities" community into a larger one yet. The name for this new community is Quora 2.
