In fact, I don't remember the details now but I recall looking at the source for another one of the suckless applications and finding some pretty inefficient algorithms. I think the other comment here about st being CPU-intensive with high output rates is an example of this.
Ironically, one of the reasons I think mainstream software sucks is because newer versions also tend to remove configurability and features often for the same goal of reducing bloat.
It's the same rationale that leads one to use a pen and paper rather than a note taking app.
I agree most of their stuff isn't targeted toward the average user, just this small niche. Their browser, surf, doesn't even support tabs as far as I can remember.
There is a general tabbing frontend that allows you to tab all sorts of applications: http://tools.suckless.org/tabbed.
I think it's fair to say suckless code is clean and minimalist. But it definitely isn't suckless.
Secondly, it's all very tongue in cheek. After all it's aimed at the OpenBSD crowd and like minded people. It's not really meant to be taken literally by the general computing audience - not even within the wider FOSS community.
Lastly it's sad day for HN when negative comments get up-voted and positive comments defending niche software get down-voted. What happened to respecting our peers and acknowledging the massively wide range of personal preferences and usage habits?
I absolutely wasn't trying to be disparaging of them. I understand that there are people who love their work, and I love some of their software (dmenu).
My point was more toward the parent I was replying to - i.e., that the message from the suck-less crowd that other pieces of software "suck" is just an opinion. In the same way that they think (for example) the KDE desktop sucks, it's allowed to think that their products suck.
But I suppose that it can be seen as disrespectful, and I understand that. There is definitely room for airing one's opinion in a less inflammatory way.
Then again, if they name their project(s) "suck less", it's completely fair to say it sucks. If they can have arbitrary standards about what constitutes suckage, why not us?
