 There are many definitions. They about all share that a meme is a 
 replicator, and thus defined by heritage. It is thus an historic 
 definition, as it is with genes. But beyond being a replicator, there 
 are many definitions. Form memes being ideas, to being behaviors, 
 to being artifacts. Since it is historci, I do not know if you can 
 speak of subsets and so on. Perhaps in memeplexes. Others have 
 ideas?<<
Finding a definition of meme, beyond just "cultural replicator" is quite a 
quarrelsome affair.  Even then people occassionally object to that because it 
sounds too active - memes are replicated they don't replicate on their own.  
But I think enough people understand that such that we can still safely say 
that memes are "cultural replicators" without causing confusion or 
disagreement.
Despite my otherwise disagreements with S. Blackmore's ideas, her book did 
introduce a meme to me called "Campbell's rule".  Which roughly says that 
memes are not genes therefore we should not expect complete correllations 
between memes and genes.  Discovering the extent that Campbell's rule does 
and doesn't apply is one effort in defining memes through abstractions, and 
it does at least give us some points of reference within biology.  A typical 
dispute over Campbell's rule would be whether memes have identifiable 
memotypes and pheMotypes that would correlate with genotypes and phenotypes 
in genes, where genotype/memotype are most associated in the process of 
selective *retention* (heredity) and where phenotype/pheMotype are most 
associated in the process of natural *selection* through manifestation.  
Without such an identifiable distinction, memeticists must then address 
accusations of Lamarckianism (how memetics is not, or if it is how that 
doesn't make any difference).  With them, memeticists can afford to be more 
unconcerned about such accusations.
Beyond these kinds of abstract arguments over definition, are arguments over 
manifestation, mechanism and measurement of memes.  Examples of manifestation 
arguments are over whether memes are "in the head", "in the environment", 
some of both, behavior, thought, or just information or some combination 
thereof.  Examples of mechanism arguments are whether memes are based 
imitation, information, or language.  People with more of a strictly 
behaviorist background might be more likely to say that memes are based on 
imitation, that they are manifest in behavior, and would probably be more at 
home with Blackmore's insistence that selves are merely meme illusions 
(whether or not they buy the rest of her Buddhist bag).  People who are more 
at home with cognitive models and semiotics might be more likely to say that 
memes are based on language, manifest in thought, and would probably be less 
inclined to accept Blackmore's insistence that selves are merely meme 
illusions (this is more of my position.)  Actual measurement of memes would 
be sensitive to how issues like these are resolved.
These are just some examples of themes, though there seem to be almost as 
many distinct definitions as there are memeticists to talk about memes.  So 
feel free to jump in.
