Is there a way to delete multiple Facebook post that I posted?

No, there isn’t. You’ll have to delete them all individually.

@Just don’t post as often.
The old posts disappear pretty quickly and only the last few can still be retrieved.

I cleared out my facebook account oh mannnn it took forever. one by one. click. click. click. click. ....

Yep, that is right: just click, click, click it is more enjoyable to play a game clicking away ;-)

I agree to post less often—I’ve committed to just posting meaningful stuff from now on (of course, everybody’s idea of what’s meaningful differs) so as not to clutter my or anyone else’s walls. I deactivated my account temporarily just because I was tired of seeing everyone else’s “what I had for breakfast” tidbits. But everyone’s right… no way (yet) to delete multiple posts AND they do not disappear as older posts are visible when you click the ‘older posts’ button at the bottom of your wall.
