I Liebe Near because of his personality. I loved L because of his strange behaviors and his cuteness, and I Liebe Near for the same reason. There's something innocent-but-not-innocent about them, and I Liebe it. :)
As for the Sekunde half of your question, yes, I do like Near. Otherwise, I would not be in his Fan club.
As for why,
I mainly like Near because of what an intriguing mind that he has. Many people detest him, claiming that he is a copy of L, and while they have petty similarities, such as quirks and social status, and the obvious similarity, high intelligence, they have very different personalities and ways of thinking and getting things done.
I also find that he can be extremely humorous. Particularly in the manga.
Last but not least, I have many connections with his character, mainly insight-wise. I noticed this from his thoughts and sayings on Kira and his supporters.
