This has always been a connundum for me. On one hand, I think it would be useful to increase the exposure of some of my ideas. On the other hand, I've seen what this does to people - especially in the current Podcast Bro culture that relies heavily on cross-promotion.
People who go around saying "Oh, I'll never be like that" are rarely being realistic. My observation on other areas of my own life is that these things really sneak up on you, and everyone tends to attract people that will reinforce the negative aspects. We all like to be liked, and it can be difficult to keep people who are eagerly trying to support you in a bad or mixed way at arm's length. Especially when they have a lot to offer in the material and / or emotional and / or friendship sense.
I'm becoming much more aggressive with defining boundaries and getting rid of people who take me in bad directions or otherwise bring me down, but I dislike doing it and the more people get pulled into your sphere the more you have to do it.
And now I realized I kind of sound like a whiny bitch, but it's still tough.
