Rarely have I seen interesting discussion happen in the comments of a personal blog. All great discussion is held in aggregators like HN.
Similarly search is best left to specialized platforms such as a search engine. Blogging software may have decent search by why recreate a search engine when duckduckgo.com will far exceed capabilities with site: and filetype:?
For me a personal site and blog are mostly single visit kind of stops. I end up on a blog via a link but almost never do I feel the need to read the top 5 best posts of some blog. I got some interesting information from the current article but then I’m of to the next link that shows up in my feed.
In my opinion a website needs readability[0] and an ATOM/RSS feed. All the rest is part ego ("my content is so great people just have to see what else I wrote") and part feature creep.
