@Miraz @manton I have a similar opinion as @miraz. To me timeline sync have been something that I really wanted to see, but my understanding after a year or two was that it was never going to happen so I shut up.
When good mastodon clients showed up, I realized how much I missed timeline sync. And I found it much easier to read the timeline when I didn't had to scroll "backwards" trying to find a post that I had read and then go forwards. This difference between Mastodon and Micro.blog has made me reading the mastodon timeline much more often than micro.blog.
And like @miraz I've tried to solve the problem using the RSS feed but then it gets really cumbersome if I want to answer a post ... so I usually just skip answering.
