Link love was the "automatic" creation link of some else' blog on your site. Whether you mention it on your post or putting them in your blogroll/blog list because you found the site very helpful or it was your friend's blog or simply it was me who you found very interesting lol :D . While in exchanging links it has to be reciprocal, where x site should appear in y site and vice-versa. But I prefer the link love because it was natural. But I'm not afraid to do link begging for an exchange link.
