The site is decided to tailor to a more professional target audience.
I'm glad this help the site. Thank you for your endurance and commitment to the site.
To a certain degree I feel shameful for being able to only take from it, not give anything. But now I'm afraid that I can't be helpful anymore, especially in the meta, in important problems. Being a layman how can I know what is useful to contributing? Will my votes becomes noise, because it is equivalent to a vote of an expert? I used to leave answers and comments on the meta, and they are somewhat useful, but from now what can I do? I can't see anything left for me to do, except asking if a topic is on-topic or not.
