Flakey

So we've slowly started to clear out some of the crap that's been lying around the house unused for years. And part of that process has been putting things up on Craigslist. We don't do this a lot, so maybe somebody can explain this one for me:

WTF is up with these no-response Craigslist people?

I post an item.

I get an email asking if it's still available.

I say yes.

And then ... nothing.

I put an ad up for a dryer last week. I got 4 responses. The first person asked if it was available and could they pick it up tomorrow evening. (Friday) Asked for contact info. I responded, and... hello? Are you coming? When are you coming? Same for a bike rack I posted on Saturday. 4 replies so far, including one saying they could pick it up "tomorrow, anytime." Not a single follow-up.

Are these people flaky or just rude?

Or is this some new sophisticated email address harvesting scheme? Eff me, if that's the case.

Either way, people suck.

Bah.

UPDATE: I had two people (TWO!) respond yesterday, 3 days after I replied to them, asking if the bike rack was still available, and maybe 2 hours after some guy took it away after responding to the post yesterday morning.

Again, WTF is up with these people?
