<p>Do you expect the OP to say “thank you?” Or not. What about e-mails? </p>
<ul>
<li>I oftentimes notice that people don’t reply with “thank you” messages - although I’m kinda used to it. And wrt threads - helpful replies could stream in for several days - and it would be awkward to post several thank you messages in the middle of the thread.</li>
</ul>
<p>Sometimes I wish people did, when I spend a while on a reply. Although I don’t generally post thank-yous myself, so it’s not so reasonable of me to expect them.</p>
<p>in PMs I definitely would.
and if I actually make a long thought out post, and search for links for the person it’d be nice to get a comment other than “BUMP! anyone else???”</p>
<p>I usually try to post a thank you to everyone who replied in posts I make requesting help.</p>
