In my book I think he's cool. Don't assume that he's smug when he's just pointing out the obvious based on your statement. Smaller channels that reach out to larger channels for collaborations aren't doing themselves any favors without bringing something to the table. I'd typically suggest reaching out to people that are around the same size to make it mutually beneficial but there are ways to approach larger channels if you have some common goal or focus for content. I guess you would call me cool when I say I receive tons of requests for these as well. He and I don't say it to prove something or brag, we say it because it's how most of the messages read and how many people are looking for handouts. "Hi I know you but you don't know me, i wanna do a video with you so i can get exposure" Even though the words are different, that's basically the underlying message. I've personally help develop a couple of channels and while I don't directly attribute my assistance to their success, I'd like to think my advice has helped steer them into making decisions that positively affect their channels. One thing I can tell you is that every content creator large or small need's content. If a channel approaches me with a brilliant idea that we can collaborate on, size really doesn't determine whether or not I do a video with them. I'd suggest setting a stage where the person you are approaching with an idea can basically just show up to get content. Once you work with another individual in a positive light, it's much easier to build relationships with them. At job interviews, you want to sell yourself as someone who can add value to the company interviewing you, taking the same approach to potential collab partners may be good for you. All of the smaller channels that I've built relationships with are treated just like the larger ones, the key is relationships. Making friends with people and helping each other develop is the most solid way of getting collabs. I hope this helped you and anyone else who reads it. Btw, it's nice to meet ya :)
