I definitely was a former H!P fan.
I got into H!P in 2008 (SO LATE!!! ><), and it kinda started out for me getting into J-Pop. I followed Morning Musume, C-ute and Berryz Koubou for a while. Of course the members I liked were Reina, Maimi, Miyabi and a few more. I watched a few TV shows like Haromoni, and I found out it would be H!P's last TV schedule due to extremely poor ratings. And also H!P had to say goodbye to the Elder Graduates like Yuko Nakazawa (H!P's granny) and Natsumi Abe (original face of MM).
..since then I started to lose interest in H!P, and it wasn't until when I discovered AKB48 in August last year, got hooked and jumped ship.
Sometimes I still keep up to date what's been happening in H!P (eg. Lin, Jun and Kamei's grad announcement). Now there is nothing left, just weekly radio shows
