It has been nearly one hundred and forty years since Baudelaire defined modernity as ephemeral, and described the artist who observed the transient images of his time as a flâneur. Even if we recognize our times as postmodern, the proposal of the author of Les fleurs du mal is still valid, especially given the variable nature of the World Wide Web, where pages or sites are as itinerant as Ulysses in pursuit of Ithaca. For the untiring flâneur of the Web, the pleasure of retracing fortuitous pages could transform into disappointment. It’s like returning to your old school and finding it in ruins, or even worse, finding in its place a sumptuous shopping center that disfigures completely the mental image that our memory had steadfastly retained. Notwithstanding the constant transformations in the appearance of the Web, there are certain sites that seem eternal due both to their excellent quality and also to the continuous effort invested in upgrading them. That is the case of the sites Jornal de poesia and Literatura Argentina contemporanea.
