I did a double take when I read that Sakura had a blog, when did that happen

turns out it was from the pokemoni tour diary xD
^I really don't think you need to worry about her not blending in with her group mates. I think most MM girls have written about spending time with Sakura in their respective blogs and the topic of her being able to make friends easily and adapt quickly to her surroundings has been mentioned quite a couple of times, just off the top of my head Sayu's KonUsaPi and the latest girls news.
