I can't see why people have such an issue with gift lists either - unless the items are all ridiculously expensive, in which case I usually go "off-list" - it's quite useful not having to wrack my brains to think of something they might like that no one else would think of.
And it's hardly a new idea, is it - it was originally to help couples set up in their new home as they wouldn't have anything - these days, with so many couples living together or having their own home already, it's hard to know what they wouldn't already have, so any hints and tips are useful.
And really, who goes to a wedding WITHOUT taking a gift? I would be so embarrassed NOT to take one - how rude! it's not a case of the couple "expecting" gifts, they know that most people are going to want to give them gifts, so they might as well get some stuff that will be useful to them or that they wouldn't have the spare cash to buy themselves.
My friend got caught up in the wrapit fiasco - she is neither posh, grasping or a cow and it is another unfortunate episode that dogged her wedding, along with losing her FIL 3 weeks prior to the wedding due to a fishing accident where he drowned. But after all, that's nothing in comparison with Georgia being invaded, so I'm sure there are a few people on this thread who think she doesn't deserve any sympathy.
