Oh I know a lot of people think she has the mos interesting personality. That doesn't mean it's true. The writers used Tali to explain the backstory of the Quarians and the Geth, and that's about it. She talks about Quarians in general, rarely giving any details about her own personal life. Compared to your other squadmates she isn't a developed character. I don't have a problem with this, but I just perplexes me that so many people swoon over her. Though maybe her lack of character development is why people like her, as it doesn't give you many reasons to hate her.
