I've been anticipating this comment :-) There are a few reasons:
1. I personally think that Loglan is a much more human language. You know, with capital letters and no overuse of the apostrophe.
2. I've been a somewhat active member of the Loglan Institute's mailing list. I still am a member, but I haven't posted anything in over twelve years, I think.
3. Back in the day, I also significantly improved the article about Loglan on the Russian Wikipedia. It had a “Good Article” badge for a few years, until a review found it “not good enough” :-/
4. Like a lot of Loglan-lovers, I think that the circumstances behind Lojban's “forking out” from Loglan are somewhat fishy. IIRC, there was some bad blood between “The Three Old Men” of Loglan and the Le Chevaliers, although my memory of the details is very holey.
