I thought it was a great visual joke until I read the perpetrator's rationale. Good joke ruined by pretentious punch line. Pseud's Corner best place for it now.

I thought this piece was satire until I started reading the comments. Now I think they should take Jim from Bath's offer to fix it for them for a couple of hundred quid. You should probably double that if you want an invoice.

Sorry Dr Law, what this is proving is that you can fool all of the art establishment all of the time. Ordinary people have more inteligence.

Best thing I saw this week.How was it done?And no,I didn't fall in as expected!

H.D., WsM,

I was ready accept this "crack" as an artwork, until I read her simplistic and oh-so literal racial-political reasoning behind it (yawn). If this kind of student angst is what's burning her up she should just go and throw some stones at the next G8 Summit.....and save us having to get out the Polyfilla.

As an artist coming from Antwerp , we had the Master Rubens. His paintings voluptious in muscle and bravoure, which I always stood in awe for the old masters. But rethinking that he was an ambassador and travelled a lot to Italy and back, there are not that many paintings who could be fully attibuted to him. It was a factory school and his pupils masters in a certain discipline, landscapes, trees , I think he sketched an idea which was excecuted and the final touch was him. You see so many famous Flemish artists who have been a scholar from Rubens going in what they were good at. Which could be have happened to Michael Angelo.

Yet another pretentious case of the Emperor's new Clothes!

Andrew, Copenhagen, Denmark

ah, the grand canyon, now that's a crack in the world. how about tumbling serota, saatchi, miro, gag on sin, and all their purchases and pronouncements into that crack. .. now that would be a vanishing act worth the price of deconstruction...

The artist should take a closer look at her own back yard.

The farc, the paramilitaries, the drugs, the failed state, the death squads, the cartels, shanty towns, corruption, et al.

That makes a nice little fissure to fall into, the turbine hall would not be big enough. Shame she fails to make any mention of it. Or is she avoiding badmouthing the cartels . . . you guess why?

And too bad the is no "British Imperialism" in Colombia to blame. But the Spanish may do, just as long as they can blame it on some one else.

Halo DS, London,

Modern art has long been a joke, see Data-ist's Duchamp's toilet. Said by a Tate's committee to be the most influential work of modern art. This has been influenced by said toilet, not the Tate's copy but the one cracked with a hammer by another artist. (Who by the way also went to Columbia and axed off his finger.)

Quentin, Reading, UK

Shibboleth is very cool, but the best part that no one mentions is watching people interact with the crack. Kids were down on their knees peering deep into it (some were examining with small binoculars), adults were straddling it and being photographed with it in various positions, and at the end of the crack, people were down on ground level trying to look under the crack to see where it dissapeared to through the wall. Everyone was commenting on what it reminded them of (the Grand Canyon, a Georgia O'Keefe painting). Never have I seen such interaction and curiosity and conversation over something like this. That human interaction and curiosity is ultimately, in my opinion, what makes a piece of art successful, outside the original explanation from the artist of what she intended it to be about.

Catherine , London, UK

I'm nervous before I even get there ! (about falling down the crack,I mean.)Is this nervy anticipation part of the installation's message,perhaps?

H.D., WsM,

I see your problem, the humidity in the halll was too low and the temperature too high, causing the concrete to dry too fast. A couple of hundred quid and I'll fix it for you. Cash, no questions, right?

Jim, Bath, UK

What is needed is a metal grill placed over the crack. I amsure a local builder could do this overnight when the Tate is closed.
Surely safety is more important than art.

This important work highlights an issue of concern to many people - shoddy builders.

Charles Thomson, London,

Modern art is at the point where it is to be considered a rather expensive joke rather than anything worth, well, anything. One wonders why we fund the arts sometimes, if this is the best it can manage. I would suggest that Salcedo is talentless and trying to gain notoriety using obvious sillness. Cracks in the floor, empty chairs, by this measure, even I could become a renowned artist. But I have rather more taste and rather more self-respect, so I would never dare to try and con the public in this fashion.

Jennifer Hynes, Plymouth, England
