<p>But why a wall message rather than a real message? Not everyone cares about popularity - some of the people I know who care least about popularity still post such messages on my wall.</p>

<p>It certainly gives the impression of correlation with popularity outside of Facebook, but my main question is - is this really the motive of nearly everyone who posts semi-personal messages on each other’s facebook walls? Some people certainly care about popularity but not everyone does.</p>
<p>rockermcr’s question was interesting - why would you reply with “fine, how are you?” on a facebook wall, rather than over PM/e-mail?</p>
<p>Not just that, here’s a message I saw someone post on someone else’s wall:</p>
<p>“For 5.) because he did examples in class for p =1 and p = 2 and those can’t be possible uniformly convergence on <a href=“well,%20I%20studied%20those%20examples%20really%20hard%20for%20the%20test,%20because%20I%20was%20still%20really%20fuzzy%20on%20the%20definition%20of%20uniform%20convergence%20really%20late%20last%20night,%20he%20kinda%20taught%20something%20that%20is%20quite%20different%20from%20the%20book%20or%20at%20least,%20modified%20in%20a%20way%20that%20totally%20confused%20me”>0.1</a> so if fn(x) can ever converges uniformly, it has to be 0 < p < 1… which makes sense… when you go back to the basic things that he emphasized over and over again in class. I was out of my mind to say that it never converges uniformly. (Because I was thinking of natural numbers only) This is a really fatal mistakes… and I can’t really integrate b.) if the answer is 0< p 
then… I’m kinda there, I said it’s 0 < p - 2 < 1 which should gives 0 < p < 3…”</p>
<p>"That guy who sits next to you. He actually takes the same bus with me every morning usually the same time. He is a math teacher for calculus in high school I think o_O;;; and I don’t know his name, but on the bus I met his wife Larua, who is in phD genome program. Oh boy, I’m so gossip, and it’s so random…</p>
<p>But I complained to him so much today on our way home… so he told me that he used to be a chem major, and we were bashing bio = claiming that it is a poorly integrated pesudo-science lol…"</p>
<p>These sort of convos seem more appropriate for PMs and I see convos like that all the time. Granted, I do enjoy reading them but do most people really write them on each other’s walls for the purpose of allowing others access them publicly?</p>
<p>
</p>
<p>Yeah - the reason is that it seems that people are a lot more comfortable using Facebook than e-mail, so it effectively means that I send and receive far more messages with Facebook than with e-mail.</p>
