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).
It does read as a little out of place in a serious post like the OP though.
It is on a human seeing level, harder to parse. If they don't want to use proper grammar and punctuation, it reflects on their seriousness and how serious I should take their writing (not at all because I'm not going to read difficult to parse text) The same goes for choosing bad fonts or colors that don't contrast enough
