There were two comments given to my posts, which could explain the problems of Seaside from a completely different perspective and much better than I did:
Richard Kulisz commented my post "Seaside standing outperforms facts":
"It seems Seaside has been infected with the same amateurish circle-jerk mentality that's corrupted Squeak from which it was spawned. It also seems to me that this has little to do with national differences and everything to do with professional vs amateur efforts. In professional circles, standards vary from place to place, but in amateur circles (eg, FLOSS) they seem to be uniformly poor."
Richard also commented my post: "Laws of life in a community":
"The conscious or unconscious selection of Leaders and their defense at all costs is a normal (even if utterly repugnant, vile and disgusting) part of every community. I've been in quite a few and I've observed this behaviour in nearly all of them. The Creators always, ALWAYS get defended.
In the case of programmers, no community of programmers can ever be diverse enough to avoid appointing gods. Wiki wiki (c2) wasn't. It's because programmers are on the whole nothing but mindless robots incapable of genuinely original thought. What's worse, the overwhelming majority LIKE this status quo.
Also, in the case of programmers, the Creator is almost always going to be a member of the community. This creates incestuous inbreeding, up to and including mutated deformed offspring."
Well, Richard, thank you very much for these interesting and valuable aspects. I feel that there is a lot of truth in these words, although I cannot judge myself, because Seaside is my first and only "community project" experience. Not a good one, though. Nor did I ever use Squeak beyond a little playing.
It all sounds very logical - taking into account that most people choose being part of a herd, a malfunction that I have never suffered from.
Seeing Seasiders as amateurish sheeples is an interesting aspect, which explains the fierce rejection of my proposals by most, without even discussing the technical facts. And it also explains why my heretic blasphemy of their gods made all my good technical arguments worthless for them.
Thank you for these insights, which, in essence, is much stronger a critique than mine.
