google doesn't update my site...

Changed title + description like a week ago! still wasn't 'changed' whenyou google search it.. wtf

I typically see changes on my site 1 to 1.5 weeks after... My friend makes an f'n change to his and within 30 mins it is in the index.... Granted there are some differences in our sites but that is a large time difference. So I feel ya. I also have an issue with google getting my sitemap and it claims that I have 16 pages blocked by my robots text.... I call BS on that since the damn thing is basically blank.
