<p>I think it is inappropriate to leave comments advising for voting (so +1 if I want to answer your title question). </p>

<p>On Meta we discuss and exchange ideas about many subjects in an attempt to promote and create guidelines that can help the site to develop.</p>

<p>People can have different interpretations, for example, about what a good question/answer is. Comments (repeatedly) pro-voting would probably annoy users and cause disagreements.   </p>

<p>It is better when people come here spontaneously to take a second opinion and make comparisons with what they already think.   </p>

<p>I rarely see comments which asks/advises voting. What I sporadically see are comments asking for the OP to accept an answer when he/she clearly speaks through comments that a specific answer solved his/her problem. </p>
