This follows up from an earlier post I wrote about becoming an ELT materials writer (a little belated, I know!), and it explores some of the ways I recommend you think about making some effective investments related to technology.
Some of these points relate to actually obtaining certain technology tools (to help materials writing/designing processes), while others explore different formats for actually delivering and marketing (or sharing, if you prefer the friendly/helpful collegial approach to things!) your ELT content.
There isn't graphic detail there or lists of specific things to buy or try, but hopefully there are some things for you to consider!
