I think they've been trying to change that recently; they've been focusing more on content creators - people like Shitty_Watercolour who are known Reddit-wide for the original content they post. As you noted, they launched a new type of profile which basically turns it into a subreddit, which they're pushing as a way for content creators to post their works easily.[0] The feature is still being developed but is now available to more people.
To be clear, the feature is a good one in concept, but I think the fact that they chose to market the feature this way as opposed to marketing it as "bringing old-school link blogs back" or similar says a lot about how Reddit wants to change its image.
