 Another reason I'm making one of these again is self-actualization. Historically I've thought very poorly of myself and agonized over anyone actually caring what I posted. Now, I'm just excited to share whatever I'm excited about or mentally chewing on, not out of self-aggrandizement, but because the stuff I find interesting is interesting because I find it interesting. It's a very cozy tautology. I'm not interested in building a following or crafting a brand: just sharing what inspires me in an honest way while still keeping some of myself to myself.
 
-Finally, I like to mark time with the discovery of artifacts. I'm always hunting for inspiring things--books, sites, objects, people--and feel an urge to catalogue them so I can be re-inspired in the future. I post on social media about these things sometimes, but social media is uniquely unsuited to reflection and later perusal. I liked Tumblr for this to an extent but never got comfy posting there; too many numbers and buttons and noise there for me to feel like I could collect my thoughts or feel like I was posting for myself instead of a hypothetical audience that might "like" something. I also don't like being beholden to corporate platforms.

 Some initial posting fodder:
 
 * Going through a decade's worth of unsorted bookmarks and posting interesting finds
-* Reviews or pre-reviews of 1990s primary "cyber media" that I collect like old academic books on hypertext culture and trashy web magazines

+Technically speaking, this is all powered by some markdown files with custom metadata embedded in it, a <100 line bash script, and a Go program for handling a little linking macro. I wanted to be able to author links in a consistent way but have sensible renderings in HTML, Gemini, and Gopher. All of this, including posts, can be found in (LINK https://git.tilde.town/vilmibm/blog this repository). I considered a static site generator...but I prefer scripting my own thing wrt blogging. It keeps me humble and I find that I don't use most of the features of off the shelf things.

-TODO: decide on link formatting/processing. Considering a (LINK _url with protocol_ _title_) macro that either replaces with anchor tag for html or creates a footnote link in gopher or gemini style.
