Would love to see this kind of categorization.

It was great when Google Plus finally implemented "Collections", can't live without them now.

I definitely agree organizational features are needed. I'd even be happy to see a simple tag cloud in the right sidebar. It would show only tags that user had utilized, and clicking on the tags would filter to show only their content with the tag in question. 
I'd hope this would be a fairly easy feature to implement, even if just as a stopgap while more detailed customization options are in development.

Yes, absolutely. Youtube is a good example (as you mentioned) with a customized landing page!... I think we also need to develop steemit's search functions overall. We have a huge mess of information that should be easier to browse and re-discover. This is definitely on their radar, right?

This will greatly improve user-experienced.

Hell yes! Totally! Personal page customization is a must going forward. If not this way, another way, but something where we can choose what data to display, and not a standard blog list page. Sections, categories, customized content adding, will make our pages more attractive and easier to manage content to find.

Absolutely, the more people you follow the harder it becomes to track favoured posters amid the short posts and the resteemed posts, something similar to the above would be ideal

It would be interesting if I could design my own covers for the groups.  I write a series, so I'd like the series cover and the links inside.  I also write using different characters, so a cover for each one of those crazies as well.  The book author types might also like the idea.

I had a chat with a couple of people at SteemFest about this. I would like to be able to organise my blog in the same way I organise my art portfolios ( I have many).  I will regularly sort through and put my best work to the top, take out work, keep separate portfolios for different reasons (interviews, selling, workshops). I want to show my best work to my followers and potential new followers, plus be able to access things easily. At the moment I have to do a search if I want to access one of my past posts as I have way too many posts to scroll. Even a 'pin to the top' function would be nice.

Great idea! 
I think this would be an awesome way to personalize your steemit profile, and to improve the experience for the writer as well as the audience.
Especially if someone writes a lot of different content (like me and you) it can get quite crowded and hard to find specific things you're interested in

I like this. Perhaps if the buckets were auto generated from the tags on the posts?
