Is there a way to get a any other bold font?
We all know that \textbf provides bold font, but, is there a way to get a softer bold than \textbf? Something not that "black."
In order to get a document with bold and "less bold" text, you need to use fonts that distinguish between the two. Here's an example with the libertine font.
\documentclass{article}
\usepackage{lipsum}
\usepackage[bold]{libertine} % <- "regular bold"
\begin{document}
\textbf{\lipsum[2]}
\end{document}

\documentclass{article}
\usepackage{lipsum}
\usepackage[semibold]{libertine} % <- "semibold"
\begin{document}
\textbf{\lipsum[2]}
\end{document}

You can also easily switch between bold and semibold within the same document (although I wouldn't recommend that) with libertineSB, which switches the font family to semibold.
\documentclass{article}
\usepackage{lipsum}
\usepackage[bold]{libertine}
\begin{document}
\textbf{\lipsum[2]}
{\libertineSB{\lipsum[2]}}
\lipsum[2]
\end{document}

libertine font, I regularly use the semibold font, and that looks appropriate to me, as I find the bold font too heavy. EDIT: I should add that I hardly ever use bold types outside of headings anyway, so semibold is heavy enough for me there. I'm not quite sure what bold text in regular text should accomplish - I personally avoid it.

There are two pssibilities you may want to consider:
1) The standard "bold" font is in fact "bold extended". You can choose a non-extended bold font using \fontseries{b}\selectfont in LaTeX.
This font is still bold, but not extended. Its main purpose is typesetting bold tabular numbers.
2) You may create a semi-bold semi-extended font with METAFONT. All you need are the parameter files (like mycmdb10.mf). Copy cmr10.mf to mycmdb10.mf, look at cmbx10.mf, and interpolate all parameters where the two files differ. The result will give you a semi-bold semi-extended version of Computer Modern Roman. If you want a non-extended version, use cmb10.mf a interpolation partner instead.
