As a user, I like when things appear to sync instantly and perfectly, such as in Google Docs.

As a developer, I hated the article and many of the comments I read thus far because:

- Having clients and a server properly sync and not lose data in the event of a network failure amounts to having a consistent distributed system which is not easy to do, and the commenters don't seem to have understood that

- I hate having written a long document and then losing it because the sync code is buggy, so the previous point becomes even more important.

So reading many of the things here has been mildly infuriating.

That being said, none of these people are likely affiliated with Linear, and given the overall quality of the product I'm pretty sure it works properly.
