user25568: From these vast lot discussions (Scope differences between biology and (biological) anthropology , What is the most appropriate forum for Biochemistry questions? , Is this site open to questions that are essentially requests for help classifying individual organisms? , Biology.SE and professional biologists? , Is it on-topic to ask for the identification of any living organism? , Plant Identification Questions , Species Identification Questions ) it seems to me, there is a problem of information sorting. (Though I've yet not any problem because I visit all-sorts of questions) but the problem with information sorting is very normal because  biology is a very vast field with so-many branches. So peoples want to focus only a particular field (not following a tag... rather follow a stream, may be biochemistry or genetics or botany or zoology or palaeontology etc. etc.) would get their posts shielded with others' . 
So, since peoples of all sub-fields of biology, have their right to take part in question-answer, yet that shields content of some-other streams; so I think the best solution is to make some new (beta) branches of Stackexchange, and biology.se , the original site, could be kept as more general questions and highly interdisciplinary questions. 
As well, I've seen much deficit of proper tags for specific field,  with respect to  most other SE branches. For say, yet here (biology.se) there is yet no tags for some broad groups for plants like bryophyte, pteridophyte, gymnosperms, etc. The tag phycology (algae) I've created (though I don't knew then that, new-tag creation is yet not recommended for me!). So quite more specific branches in SE could resolve these. 

user948: I don't understand what the underlying problem is. Biology is a relatively low-traffic site, especially when compared to the original trio of Stack Overflow, Super User, and Server Fault. Even on a busy day at work, I can generally still find time to read every single question posted on this site, yet on Stack Overflow I can maybe read 2 or 3% of the questions tagged python (more on the weekends, when the flow is slower and I have more free time).
If you are interested in only certain types of questions, it's incredibly easy to set up filters based on tags. You can add as many tags to a filter as you want, so you don't need to worry about missing a genetics question if it's only tagged molecular-genetics: just add both to your filter.
Based on the traffic, we absolutely do not need any more specialized biology-related sites. Our subject base is quite broad, and many different types of questions from many different fields are welcome here (obviously, assuming they meet our criteria of topicality and scope).
I am against creating new tags unless (as a general rule of thumb) you can tag at least 10-15 existing questions with it, if not more. Just because your question is about a specific sub-field does not mean it needs an incredibly specific tag - immunology is just fine, we don't need t-cells, b-cells, nk-cells, splenocytes, dendritic-cells, etc. etc. Likewise, we don't need a specific tag for each and every type of plant, animal, bacterium, archaeon, etc. Tags are for classifying questions and assisting in search, but Stack Exchange's search engines also include full-text keyword searching, so if you want to find all existing questions on gymnosperms, just search. 
If you truly feel like a new tag should be created, please post a question here about it and let the community weigh in. Link to all the previous questions you can find where the tag would be relevant and valuable. Explain how the new tag would add value to the site. If there's a good response, someone will create it. If not, or if there's no response, it's probably not a good idea.
