I'm probably pretty close to being in your general boat on the technical side, though I may have been at it for about 5 minutes longer. Keep pecking away and you'll get there.

I notice that you don't seem to have connected your Instagram account to brid.gy yet, though you're collecting your Instagram posts via Known (presumably with OwnYourGram). Adding your URL links (with rel="me") properly (the Instagram account in your profile on vaviblog and the other in your IG account pointing to vaviblog (either in the website field OR your description field see https://brid.gy/about#domain)) and authenticating brid.gy should let you own all your likes/comments from Instagram on vaviblog with less than 5 minutes of tinkering. It's also a simple, but motivating exercise that may make some of your slower progress on the "mothership" seem like a better fight.

Hint: Known already marks up links on your profile with rel="me" so you only need to put in the URL. Instagram doesn't support rel="me", but brid.gy routes around it on your behalf when you put it in one of the two locations described.
