Question: I like to know what you guys think about using feedback as a verb. I've seen it a whole lot in writing and email communications. What would be other alternatives? 
Your input is appreciated. 

Thank you,

Answer: 
There are plenty of situations in which new verbs can be created in English. If a noun such as "feedback" is used as a verb enough times and it sounds ok to enough people then it will be accepted as a verb. The verb "to google" comes to mind. If it doesn't sound ok to anybody then it will be considered wrong. The noun "feedback" is relatively new in the English language and, for the time being, is usually used with the verb "give". Personally I would never say "please feedback me" I would say "please give me feedback"
Feedback is a verb phrase. If you want to change the verb's tense, number, *et cetera*, you should modify "feed" separately from "back". For example:

* Feedback loops occur when the output from a system is fed back into the system.
