Perhaps, which is why I am not completely against the BBT, but I have read some websites with stimulating new ideas as you mentioned. But don't you think after 30 years of failing to detect dark matter that there should be more funding towards alternative explanations like plasma cosmology? I am not saying they should ditch dark matter but open up new possibilities.
Plasma cosmology - Wikipedia Wiki on Plasma Cosmology, interesting stuff.
I won't pretend to be an expert in this field, but that usually doesn't stop me from offering my opinion.
From my understanding, Plasma Cosmology (PC) has a fundamental problem. You have to work through the "back door" to arrive at observations using PC. That is, only in very special cases will PC produce such observations as the temperature fluctuations in the CMB. For a scientist, this sets off very loud alarms. This is starkly contrasted by the BBT in which the observations we see are the exact observations we would expect to see. The prime example is how the BBT is able to very accurately predict the characteristics of the CMB. PC doesn't even predict that the CMB should be there, and has to twist over itself to explain it.
When comparing the BBT and PC there really is no comparison. The BBT says that certain things just HAVE to be there while PC can only say that these same things could perhaps exist, or not.
And again, I am by no means an expert but this is what I have gleaned through my reading. If I am way off base please let me know.
