Some small typo edits

	<h3>Why Database Technology Matters</h3>

	<p>Sometimes I get so down in the weeds of database technology, I forget why I think databases are so fascinating to me, why I found them so important to begin with. ACID. Latency, bandwidth, durability, performance, scalability, bits and bytes. Virtual this, cloud that. Blah blah blah. Who the fuck cares?</p>

	<p>I care.</p>

	<p>Dear lord I care. I care so much it hurts.</p>

	<p>"A database is an organized collection of data, today typically in digital form." -Wikipedia</p>
