Normally I can ignore it, but the font on this blog makes it hard to distinguish where sentences start and end (the period is very small and faint).
Incidentally, millenials also used the "no caps" style but mainly for "marginalia" (at most paragraph-length notes, observations), while for older generations it was almost always associated with a modernist aesthetic and thus appeared primarily in functional or environmental text (restaurant menus, signage, your business card, bloomingdales, etc.). It may be interesting to note that the inverse ALL CAPS style conveyed modernity in the last tech revolution (the evolution of the Microsoft logo, for example).
