Back to the original question:
The question is; Does Google mind comment links in blogs and articles to relevant sites like these?
I would say, looking at a particular niche for about 6 months now, that having those kinds of comments CAN help a site rank better.
However, if that site DOESN'T ALREADY HAVE A LOT OF HEALTHY LINKS, then there is a possibility those comment links from blogs can HURT your site instead.
Also, make sure that the site you are commenting on is RELEVANT to your topic and only accepts comments that are relevant and on topic. And also make sure that they are dofollow links.
These sites all have original, legitimate, super-relevant content and most pages on the sites are 500-1000+ word pages. The sites are all user-friendly, easy to navigate, branded and designed well.
Good. Then it would probably be better to just contact relevant sites that are NOT blogs and tell them about your site and ask them if they would kindly link to your site.
I hope this helps. Having great content is 90% of the battle.
