Every so often I see people on HN use compete as if it were a reliable measurement... In my experience it's not.
Compete shows a few of my websites as declining when they are in fact growing... In one particular case it showed that a website that was tripling in traffic was declining... It's so unprecise that I often wonder if it's not just a random number generator weighted by pageranks and mentions in google trend powering compete, it seems it'd give about the same results...
Reddit is a good example of pointing out to inaccuracies of Compete.com
Still, when reporting on Reddit Compete.com is off by factor of 4 (not 10).
And the trend is shown correctly (Reddit growths).
For Blippy.com both Compete.com and comcast.com show very small numbers and Compete.com shows steep downward trend.
Unless somebody could share more reliable source of data I would assume that Blippy is on decline.
