To some extent it is as needed. I was doing them once a month for a while, but the activities in GitHub slowed down a bit, so I started doing them less. (With the developers working on communities and mobile, there haven't been as many other changes.) I think it has probably been about 6 months since the last one I did. I do still post quite a bit of other Steemit dev' related stuff though, so if you like this type of thing you probably won't be disappointed from following me :)
