I used to use Freecycle quite a bit when I lived in the city - mostly to give things away. I usually used it to give things that were maybe slightly flawed, so I didn't feel I could donate them, but I was hoping to keep them from the landfill (and I was always honest and clear about the flaws!). Things like kids clothes with small stains or holes (but great for playclothes!) or worn out towels that could be used for rags (went to a woman who wanted them for a preschool to wipe down the playground equipment) or partially used paints/stains/etc (went to a couple completely remodeling their home).
I never minded a tiny bit of 'story' - meaning, if someone just said "I'd love to use this for X". I liked that someone had an intended purpose for the thing, instead of just those handful of people that will respond to *everything*. I learned to wait a little at least and see what came up. Whenever I responded to ads, I did something similar - like "I'd love that for my daughter's room!" or "That would be great in my garden!" ....Not a big story, but letting the person know I really intended to use the item for something. Also, being clear about when you are available to pick up the item is HUGE!!!
That said, I think I only ever got a few things from Freecycle, and those were usually things I posted a "wanted" for. Right now I am seeing out of the corner of my eye a step stool I asked for. I remember when DD was between 2-3 and wanting to use the sink herself, I was trying to find one, and offended by the cost of buying a new one LOL. I posted that I needed one for my child who was ready to use the sink herself. Someone in my neighborhood responded, who had now grown kids and gave me the stool that had been theirs. :)
I kind of miss it actually. Now that I am in a more rural area, it doesn't make sense to have people drive to your place. Instead I take everything to a great local thrift store that is associated with the food bank. Haven't quite figured out what to do with the slightly flawed items though!!
