 <li>blessfrey.me's diary properly displays snippets for all articles: a header taken from the title, a truncated view of the article, the date + a place for social media share links, and a link to the article.</li>
 <li>Cleaning the snippets enough to look okay and not break the page was a challenge. I used regular expressions to remove html link + header tags, <a href="https://stackoverflow.com/questions/1732348/regex-match-open-tags-except-xhtml-self-contained-tags">which is apparently a lost cause Stack Overflow users stand against daily, hourly even</a>.

 <li>First command line git merge. I usually do it on the website. It's really simple - switch to the branch you're merging the second branch into, type 'git merge second-branch' (second-branch = name of the second branch obviously), and fix any conflicts.</li>
