The Twitter experience is a highly algorithmic feed where tweets from the people you follow are not guaranteed to be in chronological order, or even shown to you at all. The default experience also mixes it other tweets "you might be interested in", that is, things they want you to see.

There's also the fact people could freely see tweets and follow discussion threads, that's now locked behind an account requirement.

It's obvious that people outside of the areas where transport is dense enough won't enjoy all the benefits. This is a usual complain about all dense public transport areas, but it simplifies to the fact that you were not in the area with dense coverage. In the case of Madrid, Metro is only dense enough in areas surrounded by the Circular line. There's also a very dense bus network that covers everywhere within M-40 and even some areas outside it (some bus lines can be hindered by traffic though, there are bus lanes in most critical spots but there's always some unpredictability).

Also, you're wrong on the closing time, it's been 1:30 AM for a long long time. That's the time where the last train departs on each line, so it's possible to catch trains at almost 2 AM depending on where you are. By Madrid standards, if you are out and about at 1 AM it means you are in a bar or in a party, and it's time to decide whether to continue through the night and get back when Metro opens again at 6 AM, to use a taxi to get back home, or to use the night bus network if you're lucky to be near a stop and willing to wait for it.

The benefits of good public transport are so mind blowing that it's difficult to explain unless you have lived on a city that has it.

Lower spec speakers have become good enough, and DSP has improved to the point that tiny speakers can now output mediocre/acceptable sound. The effect of this is that the midrange market is kind of gone, replaced with neat but still worse products such as soundbars (for AV use) or even portable speakers instead of hi-fi systems.

On the high end, I think amplified multi-way speakers with active crossovers are much more common now thanks to advances in Class-D amplifiers.

If you want to avoid the extra space, it's as easy as using a 16:10 resolution size. The menubar will drop down to the 16:10 space.
