Comprehensively looking at the resent development, contemporary art is successively nothing to the medium itself. Cross-media, hyper-text, cynic, refuse, rejecting the rule…seems to place the art itself to be a diverse and multi-position on the way to an illuminable area.

虽然当代艺术发展至今日己不存在所谓媒体意义的问题，跨媒界/超文本/违规/犬儒/否定/拒绝…多元无而定向的特质令艺术走向无边的领域。

The split between the two groups can hardly be papered over.

这两个团体间的分歧难以掩饰。

This approach not only encourages a greater number of responses, but minimizes the likelihood of stale groupthink.

这种做法不仅鼓励了更多的反应，而且减少跟风的可能性。
