This! Like the dreaded lazy "let's do something this month" in plotting posts, a CR meme post that gives more concrete ideas will grab my interest faster while I'm wading through a flood of "I need friends". Also it's good to say what kinds of CR you're looking for ("I need friends" for example) just to show who is open for what. Just saying that going the extra mile of talking about what you have to offer other people really helps it stand out. If they're engaged with the setting and show an interest in sharing that with other players that tells me they have exactly the collaborative attitude I like to see in this hobby.
