Comments are designed to be temporary clarifications about specific questions/answers and as such are cleared at regular intervals.

As the Comments privilege page mentions

• Comments are temporary "Post-It" notes left on a question or answer.

 

Comments are not recommended for any of the following:

 

• Suggesting corrections that don't fundamentally change the meaning of the post; instead, make or suggest an edit;

 
• Answering a question or providing an alternate solution to an existing answer; instead, post an actual answer (or edit to expand an existing one);

 
• Compliments which do not add new information ("+1, great answer!"); instead, up-vote it and pay it forward;

 
• Criticisms which do not add anything constructive ("-1, see previous comments you scallywag!"); instead, down-vote (and provide or up-vote a better answer if appropriate);

 
• Secondary discussion or debating a controversial point; please use chat instead;

 
• Discussion of community behavior or site policies; please use meta instead.
