I would like to summarize what has been said in comments above.
It is not acceptable on MO to ask general questions about research in given area of mathematics. Most MO users see the value in fact that only specific questions about mathematics can be asked.
It is acceptable to ask for a survey - it is general description of research in given area of mathematics. Good survey should also contain directions in which research should continue. It should also contain open issues to be solved. If given MO user do not know which way to go then he/she should read the survey in order to find out. Ultimately he/she can start journey in some direction on his/her own risk without bothering MO.
