It's pretty low, but any start is good. Just keep adding quality pages, getting referrals, and, if of interest, building more sites.
I think that starting with a low weight and growing it is almost better. You will need to increase that at some point. I think I started at around 24 (yes 24 not 24k) and over the last few months have increased that to about 75K Just keep SEOing the sites you have it on to be sure its fully indexed
well i just updated my ads and did them so they showed 3 ads instead of just 1 and my weight shot up 2 4.9k so thats a good boost rite
