The real question is, what anchor text are you using? If you are using branded phrases and their variations as anchor text, you are safe. If you're using money keywords, then be cautious as there have been thousands of websites penalized under the wrath of Google'e Penguin update, most of them because of "anchor text over-optimization", using same anchor text (money phrases) for a large number of times.

A few things to consider here while you're building these web 2.0 links:

1. A newly created blogger.com property with one unique article wouldn't have much link juice to pass on to your money site, unless that unique piece of content goes viral and you get sh&t load of links pointing to your blogger.com site. Oh, and in case you're really writing content that can go viral and drive links, you should actually be posting it on your money site, not on any 3rd party site.
2. Initially, when you link to your money site from this not so highly authoritative site, you are doing nothing but creating a bunch of links from sites that have no to little authority. Easy to identify it as a link network post penguin.
3. Instead, you might want to create some authority on these sites, and then link to your money site, passing some link value.

In general when you're building links, look at the complete link profile, not individual links. Google will consider your complete link profile while giving you credibility, authority, rankings, etc. Building a few links here and there with whatever anchor text wouldn't matter much. What really matters is what % of your overall links have the exact anchor text or close variations.
