  1. memang kebanyakan mereka lagi emosi tinggi.

    tentang pulau jemur pun kutulis "Jangan-jangan ini kerjaan iseng travel selangor malaysia ngawur untuk mendapatkan trafik pengunjung web. Cara curang dalam dunia maya."

    dan ternyata rupanya kesalahan admin yang belum mengerti posisi pulau. dan permasalahan telah di konfirmasi ke pihak admin oleh beberapa blogger dari Jawa.

    Temen2 dah mulai mengerti bahwa kesalahan itu merupakan kesalahan orang-perorang (oknum) bukan kesalahan bangsa.

    salam sejahtera
