My experience is: As long as you don't write about something really controversial you won't get negative feedback. Frankly, in the beginning you may not get any feedback at all So, beside of disabling comments I'd suggest to start writing about something where no one can have really strong opinions.

Blogging is a great experience and people are really friendly out there. Try it out!
