Introductions are never stimulating, but unfortunately it is the job of new members of the group, so abide by my ensuing unclear blather. Sorry for the odd phraseology, but the current passage is put forward in... quite unusual circumstances. The puzzler talking to you, lover of reality shows and parlamentarianism (largely impertinent to the group in consideration), at the present is going through the manifestation of one utterly exceptional panic or mania: not related to triskaidekaphobia, but not further totally unalike.
To outline me, an image was put in the fancy imgur place of yours, but the key was encoded by one routine whose title is not pronounceable to me. Maybe if one puzzler truly follows my trouble, he or she could unearth my message:
So apprise me, puzzler: after the prattle above, how would you portray me?
The key to the encoded message are the first 5 of my favored letters in English. A(3-2)Z(29-3) might point to which those are.
Tip two (out of persona):
(7): this is one part definition, one part terrible pun.
(8,7): mathematics reference, but a fairly well-known one
(7): Think simpler for this one.
