Sure the hosts probably didn't try to talk to them much in this episode, but I mean what can you expect? Gocchin (Taka's fav btw) was there, and then Johnson with her baby news, and Burriko Nacchi. It was a bad set-up to begin with. Everytime OG's are there, they automatically take more priority over the newer girls.
lol So I dunno why everyone is blaming Taka and Nakai for not interacting. If the girls want to be heard from, then they'll do what they have to in order to get their screen time. Even if that means violating/disrespeckin' an OG (Kago punching Gooch in the crotch comes to mind. Rude, but extremely LOL.) I mean, there were plenty of times in the past where the hosts did reach out to these girls, maybe by teasing them or whatnot, in an attempt to get something funny out of them, but the girls didn't know what to do with it. Maybe after all of that trying and being funny on their part, they just gave up since it was rarely being reciprocated. So it's the girls responsibility now to make the hosts, and the public like them, and wish to interact with them. You aren't always going to be given a chance, and so you have to make one for yourself. I really just think that the current line-up doesn't want it enough.
