  • Speaking in general about life experiencePeter has been to Europe many times.
  • Speaking about events that happened recently and influence the present momentI've already eaten lunch.

blog colaborativo

un blog colaborativo es aquel en el que puede una entrada o publicacion ser editada por uno o màs autores, es por eso que se llama "colaborativo" pues entre muchos autores aportan ideas para hacer una publicaciòn y de misma forma està respaldado.

en el caso de un blog colaborativo educativo, son varios profesores quienes hacen las publicaciones, y una principal caracteristica del mismo es que los autores deben de tener un interes comun y una misma finalidad para poder compartir ideas y asì poder ser publicadas.

en el blog colaborativo, a diferencia de un blog convecional, no solo el creador puede editar sus entradas, si no que tambien el decide a quienes darles "el poder" de poder editar, complementar, o quitar informacion de cierta entrada.

welcome
