I think you are confusing development with GitHub activity. A lot of meaningless commits can be made in order to create the appearance of active development, and not all development surrounding a coin is being made in a single repository. Litecoin's latest commit was actually made before Dogecoin's, and both projects have incredibly active communities. Both coins regularly have 50k active addresses on any given day. They are hardly "abandoned" by any sense of the term. Perhaps they are just relishing the status of not being broken, and as they say, "if it ain't broke, don't fix it."
that is a good point but as i said i did actually look at individual commits and they don't look meaningless ones to me.
you are also confusing social media with community and development. the Dogecoin "community" is mainly traders not developers who are interested in making profit or those who are having fun with the jokecoin. also the problem with "copycoins" is that they never really did that much development in first place. both LTC and Doge are copycoins. LTC copied bitcoin and DOGE copied LTC.
DOGE is not abandoned by traders but it is abandoned by developers when last commit was made 8 months ago. and their yearly commit count doesn't even fit in one page!
