I've recently started using SoulSeek and openly share a lot of my content. It can prove helpful when looking for certain titles, and the whole, 'share and share alike', incentive is a good one to have, but as is often the case, there are those who place conditions and restrictions upon that which they want to share, (something I must stress that they're entirely entitled to do and as such is their perogative), but it does leave some of us mere mortals in the library music sharing pool feeling a little left out in the cold. But then, that's kind of the nature of the beast, I guess. People use it as they see fit for their own needs. There's no right or wrong way to use it.
