Thanks for this feedback!
Is this a motivation to use more often questions in title? I must admit that I rarely do that, but if you now tell me that this is much more appealing, I will definitely reconsider.
I find I much more enjoy these introductory posts of yours, probably because I can understand them much better!
I agree that I should write those more often. Even if the topic has been covered several times in the past, such posts provide good reminders to new readers, are always more accessible than those in which I discuss my own research works. However, it is not always easy to bring something more, that was not there in previous posts, so that each post keeps its seeds of originality.
Anyway, this is well noted and I will try to go back regularly to the basics. The quest for the Higgs boson will be the next of such topics (as on July 4th, its discovery will be 10 years old).
