Shame they’ve ditched Hacker really, as Phil Fletcher was superb at ad libing and they become some of the funniest bits of the show. I presume he’s still used by CBBC Pres? Although, haven’t all TV shows he used to do been canned?
I did wonder if they’re phasing Hacker out, as “he” seems to be building an online presence issuing Twitter/Instagram/YouTube videos!
It might well be that Hacker's ditched the show, rather than the other way round. It's not the most appealing gig - I wouldn't fancy getting up early on a Saturday morning then hanging around for two and a half hours for about 20 minutes in total on screen. When it was simulcast on BBC Two, it probably had more allure as a showcase on "terrestrial", as Hacker calls it, but that's gone now.
Hacker still does CBBC links, and guest presented some episodes of the latest series of The Dog Ate My Homework.
