In my experience, and judging from the experience of people I know, if you are quite mainstream (not intended as an insult!) - have mainstream interests, tastes, preferences, views you will fair better than if you are a bit more 'niche'.
That's largely because a lot of the men doing OLD want a woman who dresses a certain way, looks a certain way, listens watches mainstream telly, listens to mainstream music - in short, is predictable to them, who they regard as being 'drama free' and won't embarrass them in any way.
They don't like women who challenge them or make them feel inferior or insecure about who they are.
Eg. They might take the piss that you want to watch reality TV and are interested in sleb gossip but, in the main, they'd rather that than you like art house cinema, obscure bands or have a distinctive style of dress.
That's because, as others have said, a lot of them want a wife/replacement wife who is no bother. They see 'individuality' (ignoring that we are all 'individuals') as a warning beacon that you might be hard to handle and have your own mind. They want someome who will make their life easier (in their eyes this looks like someone who stays at home while they go to the pub a few nights a week) not someone who is going to pursue their own life and interests.
Yes, this is a very broad generalisation and doesn't apply to meeting people in real life, nor to every man doing OLD but when it comes to OLD, from what I've seen, the more middle of the road you are the more successful you'll be.
