Rob Russell<p>Had a lot of great conversations yesterday at the <a href="https://mastodon.cloud/tags/TailscaleUp" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>TailscaleUp</span></a> conference with some new folks and some I haven't seen in a while. Felt like I was around a bunch of people with the same problem-solving outlook. It reminded me of what I like about tech and the internet. Thanks to <span class="h-card"><a href="https://hachyderm.io/@tailscale" class="u-url mention" rel="nofollow noopener noreferrer" target="_blank">@<span>tailscale</span></a></span> for putting it all together.</p>
