I'm always gathering links for articles, be it a blog post, or an academic pdf article.
Currently I've been using pocket, but it seems that I've been losing some articles.
Also, there are some features I'd like to have such as searchable content, or the means to save tweets and facebook posts.
This kind of sounds like Evernote, but since the changes to their payment scheme I haven't been following them.
But custom solution ideas are also nice...
If I don't have time to read it, I'll skim it. Same with youtube videos, if I don't have time I'll skip through it or play-it-back faster. I use pinboard though after I've either skimmed an article I found interesting, or read it. Exception is with reddit and medium, I don't use pinboard for those sites, rather I use their built in tools.
For ongoing projects / links I use often, those go in google chrome bookmarks. I don't really have a searchable archive except for my note's app, pinboard, and google.
If you want to save tweets or posts, just put a like on them so you can check your profile → your likes. If you want to take it further, go scrape yourself.
