What Changes Changes Be

I think someone really in need and willing to accept donations (not as likely as it might seem) would probably ask for themselves
While I am perfectly willing to donate to help with the continuing provision of a service that I wouldn't mind actually having to pay for anyway, people will usually fund things that they care about without being given encouraging pokes about it by their friends

Most people don't really appreciate even people they like pointing them towards where they should be throwing their money, good cause or no
