Why are there so many food blogs?

Is it just my perception, or are there a plethora of food blogs, more so than of other topics? I know it might be because I´m interested in food, and that´s why I find so many. But seriously, I could find ten a day, with recipes and stories that I´m looking for, and keep on this way for at least a year….It´s incredible! Is it a fad? Is it nostalgia? Is it psychological motivation, yearning for the simple pleasures of life (though some recipes are hardly simple)? Or all of the above?
