+¡Hola!, acabas de aterrizar en mi cápsula, puedes tomar asiento donde gustes.
+Me presento, en el mundo de los internets decidí que mi apodo sería "kirbylife" y de vez en cuando me gusta escribir sobre cosas de programación y todo lo relacionado con las computadoras en general, y para hacerlo me creé un blog en la web de los hipertextos y por fin decidí a traerla a este otro espacio de internet, espero les guste lo que leen y, con un poco de suerte, le encuentren utilidad.
