Hi friends i have one doubt in blogging. I have different kind of blogs(hacking,java program,entertainment.) shall i join it together And post all in single post or shall i post them in corresponding blog? My clear question is that shall i post off topic articles in my blog.
I suppose that the articles in your blog should be close to the theme.. off topic ones might not be good for your visitors.
Niche marketing is how you make money online. So you should separate the blogs to build a laser targeted audience.
Your blog topics are way "different" from each other. It's much ideal to separate blogs according to topics/niche
No doubt keep them away from each other... there is nothing worse than a blog that has no standard topic
IMHO its great to have the separate blogs, but user experience aside, do you have time to optimize each of them separately? and if you bring them together, are you concerned that external links to each of the sub-domain pages wont have the same power as if links where pointed to three separate home pages. My main concern would probably be that a few forums etc dont allow you to post links to sub-domains. third point ... if the URLs in your signature are the ones you are talking about, then capital H yes, they are way too different!
