Simi the way you write is not vulgar at all. I have read things way worse. Yours is not bad at all. If one had time to go on fanfiction.net they would say that is vulgar! Compared to stuff on that site, yours is pg-13.
There is less readership because people have stopped coming to the forum. Whether it's because there are no more new shanak scenes or they got disappointed with the rushed ending, or real life issues creep in.
I personally got a new job and I have to work more days now. When the show was on air the forum was more active, there were more active threads. The fact that you almost completed another 150 pages is remarkable because the activity on this forum has decreased tremenously! I never made it past 52 pages when the forum was active! So kudos for your efforts and please keep writing!
