Or it means that among the hobbies you have that consume your free time, there is &#x27;tech&#x27; as a line item. There&#x27;s nothing wrong about doing research in tech in one&#x27;s free time if that what they enjoy doing.<p>It&#x27;s really annoying to read replies like yours that systematically suggest all people who spend time researching and side-projecting stuff about tech are doing so because they have lot of free time or are cannon fodder. If you prefer to spend your free time gardening or brewing beer, that&#x27;s fine. It&#x27;s equally fine if I enjoy spending my own time learning about more tech stuff.
