Most probably as a consequence of ikegami's reply to your node, you updated it, by deleting everything. Please don't. As a consequence we now have an empty node, which looks awkward, and ikegami's comment seems to come out of... well, nothing. In the future, please use something like <strike> tags to "delete" (parts of) your posts, while still making their content visible for reference, and/or add visually distinctive "update" markers, like thus:

• striked out posts of mine;
• updated posts of mine.
