I think Bussu it´s good and didactic for me
busuu is boring because there are no news topics and the workind method is always the same....
furthermore, for the english grammar,I think that course are very poorly done (this is my main problem in english) and I often have to ask to my busuu friends to help me !
however busuu allows to meet very interesting person with another culture and that it's all except boring !!!
( sorry ,I translate word by word,and it's a bad strategy :) )
cyril, french, new member of this group, nice to meet you...
