Footnotes without numbering and without horizontal rule

Question

This is similar to Footnotes without numbering question here Footnotes without numbering but it won't let me add a comment and this isn't an answer..

When I add \let\footnoterule\relax as in order to suppress the horizontal rule as suggested in the comment to the answer, such as this MWE:

\documentclass{article}
\let\svthefootnote\thefootnote
\textheight 1in
\newcommand\blankfootnote[1]%
  {%
  \let\thefootnote\relax\footnotetext{#1}%
  \let\footnoterule\relax%
  \let\thefootnote\svthefootnote%
  }%
\let\svfootnote\footnote
\renewcommand\footnote[2][?]%
  {%
  \if\relax#1\relax%
    \blankfootnote{#2}%
  \else%
    \if?#1\svfootnote{#2}\else\svfootnote[#1]{#2}\fi%
  \fi
  }
\begin{document}
First Footnote here\footnote[]{footnote 1} next footnote\footnote{footnote 2}
Force footnote number 5 here\footnote[5]{footnote 3 numbered 5}.

Another\footnote[]{footnote 4} footnote here.

And foot note\footnote{footnote 5} 5 here.
\end{document}

It suppresses the horizontal rule for all footnotes. How can I suppress the horizontal rule for some footnotes but not others?

Answer 1

Just for fun:

\documentclass{article}
\usepackage{newfloat}
\DeclareFloatingEnvironment[fileext=cmt,placement=b]{Comment}
\setcounter{bottomnumber}{3}% max bottom floats per page
\newcommand{\comment}[1]{\begin{Comment}\normalfont\footnotesize\parindent=\bibindent #1\end{Comment}}

\usepackage{lipsum}

\begin{document}

Comment here\comment{First comment} plus some more text.

\lipsum[1-5]

Second comment.\comment{Second comment}

First footnote.\footnote{First footnote.}

\lipsum[6-10]

\end{document}
