Anyone looked at their midheaven's persona chart?

I have once last year but I forgot all that was on it...so I checked again and noticed I have a stellium in my seventh house: http://www.astro.com/tmpd/cfbifileul...56343.5587.gif

I don't know what it means exactly but I think it's interesting since my midheaven is empty of planets and it only has a Uranus trine to it... Also my sun, pluto, and Chiron all oppose my MC so I have a feeling that makes my Midheaven kind of weak?

To add on, my midheaven's ruler activates my sun/moon midpoint exactly: http://www.astro.com/tmpd/cfbifileul...5598.32380.gif

I am also curious what's in other's Midheaven Persona and how it has affected their life...I can't really say much for myself since I'm only 17 and my midheaven related life probably won't start till I'm 18 (because of family reasons)
