"A second brain, for you, forever. Obsidian is a powerful knowledge base on top of a local folder of plain text Markdown files. " I have no idea what that means and a quick perusal of the site doesn't really tell me what this is, If you want more people to download this please do a better job of explaining what it is. Is this a tool for Markdown writers? A a journaling tool? Does it cache my browsing experiences? Why can't people write marketing copy in user-centric terms? I'm going to try in only because everyone here seems to love it, but wouldn't bother if that wasn't the case. Please step back and think about how to introduce new products to new visitors, thanks.
