| * scrolling text

| Not very advanced by todays standards, but unbeknownst to me at

| I've seen A LOT of posts of demoscene here on HN through the

| curious.

| also not the most accessible since there's some technical skill

| youtube/soundcloud/others and the modern cross-site web

| How so? Not sure if you said that partly tongue in cheek, but

| summarize them with a single word counterproductive.
|
| In this context, the deadline section is referring to being
| ready for a demo party, possibly as a compo entry, which
| happens on a specific date, so what would even be an
| alternative to having a deadline? The writing wasn't urging the
| reader to choose whether to use deadlines, it was saying pay
| attention to the fact that your demo showdown is coming up on a
| day picked by someone else, so plan accordingly. Right?
